• Looking into ASP.Net MVC 4.0 Mobile Development - part 1

  - by nikolaosk

  In this post I will be looking how ASP.Net MVC 4.0 helps us to create web solutions that target mobile devices.We all experience the magic that is the World Wide Web through mobile devices. Millions of people around the world, use tablets and smartphones to view the contents of websites,e-shops and portals.ASP.Net MVC 4.0 includes a new mobile project template and the ability to render a different set of views for different types of devices.There is a new feature that is called browser overriding which allows us to control exactly what a user is going to see from your web application regardless of what type of device he is using.In order to follow along this post you must have Visual Studio 2012 and .Net Framework 4.5 installed in your machine.Download and install VS 2012 using this link.My machine runs on Windows 8 and Visual Studio 2012 works just fine.It will work fine in Windows 7 as well so do not worry if you do not have the latest Microsoft operating system.1) Launch VS 2012 and create a new Web Forms application by going to File - >New Project - > ASP.Net MVC 4 Web Application and then click OKHave a look at the picture below  2) From the available templates select Mobile Application and then click OK.Have a look at the picture below 3) When I run the application I get the mobile view of the page. I would like to show you what a typical ASP.Net MVC 4.0 application looks like. So I will create a new simple ASP.Net MVC 4.0 Web Application. When I run the application I get the normal page view.Have a look at the picture below.On the left is the mobile view and on the right the normal view. As you can see we have more or less the same content in our mobile application (log in,register) compared with the normal ASP.Net MVC 4.0 application but it is optimised for mobile devices. 4) Let me explain how and when the mobile view is selected and finally rendered.There is a feature in MVC 4.0 that is called Display Modes and with this feature the runtime will select a view.If we have 2 views e.g contact.mobile.cshtml and contact.cshtml in our application the Controller at some point will instruct the runtime to select and render a view named contact.The runtime will look at the browser making the request and will determine if it is a mobile browser or a desktop browser. So if there is a request from my IPhone Safari browser for a particular site, if there is a mobile view the MVC 4.0 will select it and render it. If there is not a mobile view, the normal view will be rendered.5) In the  ASP.Net MVC 4.0 (Internet application) I created earlier (not the first project which was a mobile one) I can run it once more and see how it looks on the browser. If I want to view it with a mobile browser I must download one emulator like Opera Mobile.You can download Opera Mobile hereWhen I run the application I get the same view in both the desktop and the mobile browser. That was to be expected. Have a look at the picture below 6) Then I create another version of the _Layout.mobile.cshtml view in the Shared folder.I simply copy and paste the _Layout.cshtml  into the same folder and then rename it to _Layout.mobile.cshtml and then just alter the contents of the _Layout.mobile.cshtml.When I run again the application I get a different view on the desktop browser and a different one on the Opera mobile browser.Have a look at the picture below ?he Controller will instruct the ASP.Net runtime to select and render a view named _Layout.mobile.cshtml when the request will come from a mobile browser.?he runtime knows that a browser is a mobile one through the ASP.Net browser capability provider. Hope it helps!!!

• ASP.NET Web API - Screencast series with downloadable sample code - Part 1

  - by Jon Galloway

  There's a lot of great ASP.NET Web API content on the ASP.NET website at http://asp.net/web-api. I mentioned my screencast series in original announcement post, but we've since added the sample code so I thought it was worth pointing the series out specifically. This is an introductory screencast series that walks through from File / New Project to some more advanced scenarios like Custom Validation and Authorization. The screencast videos are all short (3-5 minutes) and the sample code for the series is both available for download and browsable online. I did the screencasts, but the samples were written by the ASP.NET Web API team. So - let's watch them together! Grab some popcorn and pay attention, because these are short. After each video, I'll talk about what I thought was important. I'm embedding the videos using HTML5 (MP4) with Silverlight fallback, but if something goes wrong or your browser / device / whatever doesn't support them, I'll include the link to where the videos are more professionally hosted on the ASP.NET site. Note also if you're following along with the samples that, since Part 1 just looks at the File / New Project step, the screencast part numbers are one ahead of the sample part numbers - so screencast 4 matches with sample code demo 3. Note: I started this as one long post for all 6 parts, but as it grew over 2000 words I figured it'd be better to break it up. Part 1: Your First Web API [Video and code on the ASP.NET site] This screencast starts with an overview of why you'd want to use ASP.NET Web API: Reach more clients (thinking beyond the browser to mobile clients, other applications, etc.) Scale (who doesn't love the cloud?!) Embrace HTTP (a focus on HTTP both on client and server really simplifies and focuses service interactions) Next, I start a new ASP.NET Web API application and show some of the basics of the ApiController. We don't write any new code in this first step, just look at the example controller that's created by File / New Project. using System; using System.Collections.Generic; using System.Linq; using System.Net.Http; using System.Web.Http; namespace NewProject_Mvc4BetaWebApi.Controllers { public class ValuesController : ApiController { // GET /api/values public IEnumerable<string> Get() { return new string[] { "value1", "value2" }; } // GET /api/values/5 public string Get(int id) { return "value"; } // POST /api/values public void Post(string value) { } // PUT /api/values/5 public void Put(int id, string value) { } // DELETE /api/values/5 public void Delete(int id) { } } } Finally, we walk through testing the output of this API controller using browser tools. There are several ways you can test API output, including Fiddler (as described by Scott Hanselman in this post) and built-in developer tools available in all modern browsers. For simplicity I used Internet Explorer 9 F12 developer tools, but you're of course welcome to use whatever you'd like. A few important things to note: This class derives from an ApiController base class, not the standard ASP.NET MVC Controller base class. They're similar in places where API's and HTML returning controller uses are similar, and different where API and HTML use differ. A good example of where those things are different is in the routing conventions. In an HTTP controller, there's no need for an "action" to be specified, since the HTTP verbs are the actions. We don't need to do anything to map verbs to actions; when a request comes in to /api/values/5 with the DELETE HTTP verb, it'll automatically be handled by the Delete method in an ApiController. The comments above the API methods show sample URL's and HTTP verbs, so we can test out the first two GET methods by browsing to the site in IE9, hitting F12 to bring up the tools, and entering /api/values in the URL: That sample action returns a list of values. To get just one value back, we'd browse to /values/5: That's it for Part 1. In Part 2 we'll look at getting data (beyond hardcoded strings) and start building out a sample application.

• ASP.NET MVC, Web API, Razor, e Open Source (Código Aberto)

  - by Leniel Macaferi

  A Microsoft tornou o código fonte da ASP.NET MVC disponível sob uma licença open source (de código aberto) desde a primeira versão V1. Nós também integramos uma série de grandes tecnologias de código aberto no produto, e agora entregamos jQuery, jQuery UI, jQuery Mobile, jQuery Validation, Modernizr.js, NuGet, Knockout.js e JSON.NET como parte integrante dos lançamentos da ASP.NET MVC. Estou muito animado para anunciar hoje que também iremos liberar o código fonte da ASP.NET Web API e ASP.NET Web Pages (também conhecido como Razor) sob uma licença open source (Apache 2.0), e que iremos aumentar a transparência do desenvolvimento de todos os três projetos hospedando seus repositórios de código no CodePlex (usando o novo suporte ao Git anunciado na semana passada - em Inglês). Isso permitirá um modelo de desenvolvimento mais aberto, onde toda a comunidade será capaz de participar e fornecer feedback nos checkins (envios de código), corrigir bugs, desenvolver novos recursos, e construir e testar os produtos diariamente usando a versão do código-fonte e testes mais atualizada possível. Nós também pela primeira vez permitiremos que os desenvolvedores de fora da Microsoft enviem correções e contribuições de código que a equipe de desenvolvimento da Microsoft irá rever para potencial inclusão nos produtos. Nós anunciamos uma abordagem de desenvolvimento semelhantemente aberta com o Windows Azure SDK em Dezembro passado, e achamos que essa abordagem é um ótimo caminho para estreitar as relações, pois permite um excelente ciclo de feedback com os desenvolvedores - e, finalmente, permite a entrega de produtos ainda melhores, como resultado. Muito importante - ASP.NET MVC, Web API e o Razor continuarão a ser totalmente produtos suportados pela Microsoft que são lançados tanto independentemente, bem como parte do Visual Studio (exatamente da mesma maneira como é feito hoje em dia). Eles também continuarão a ser desenvolvidos pelos mesmos desenvolvedores da Microsoft que os constroem hoje (na verdade, temos agora muito mais desenvolvedores da Microsoft trabalhando na equipe da ASP.NET). Nosso objetivo com o anúncio de hoje é aumentar ainda mais o ciclo de feedback/retorno sobre os produtos, para nos permitir oferecer produtos ainda melhores. Estamos realmente entusiasmados com as melhorias que isso trará. Saiba mais Agora você pode navegar, sincronizar e construir a árvore de código fonte da ASP.NET MVC, Web API, e Razor através do website http://aspnetwebstack.codeplex.com.  O repositório Git atual no site refere-se à árvore de desenvolvimento do marco RC (release candidate/candidata a lançamento) na qual equipe vem trabalhando nas últimas semanas, e esta mesma árvore contém ambos o código fonte e os testes, e pode ser construída e testada por qualquer pessoa. Devido aos binários produzidos serem bin-deployable (DLLs instaladas diretamente na pasta bin sem demais dependências), isto permite a você compilar seus próprios builds e experimentar as atualizações do produto, tão logo elas sejam adicionadas no repositório. Agora você também pode contribuir diretamente para o desenvolvimento dos produtos através da revisão e envio de feedback sobre os checkins de código, enviando bugs e ajudando-nos a verificar as correções tão logo elas sejam enviadas para o repositório, sugerindo e dando feedback sobre os novos recursos enquanto eles são implementados, bem como enviando suas próprias correções ou contribuições de código. Note que todas as submissões de código serão rigorosamente analisadas ??e testadas pelo Time da ASP.NET MVC, e apenas aquelas que atenderem a um padrão elevado de qualidade e adequação ao roadmap (roteiro) definido para as próximas versões serão incorporadas ao código fonte do produto. Sumário Todos nós da equipe estamos realmente entusiasmados com o anúncio de hoje - isto é algo no qual nós estivemos trabalhando por muitos anos. O estreitamento no relacionamento entre a comunidade e os desenvolvedores nos permitirá construir produtos ainda melhores levando a ASP.NET para o próximo nível em termos de inovação e foco no cliente. Obrigado! Scott P.S. Além do blog, eu uso o Twitter para disponibilizar posts rápidos e para compartilhar links.

• Admin Panel like Custom Framework

  - by bhuvin

  I want to Create a Framework , like Admin panel , which can rule almost all the aspects of what is shown on the frontend. For an (most basic) example: If suppose the links which are to be shown in a navigation area is passed from the server, with the order and the url , etc. The whole aim is to save the time on the tedious tasks. You can just start creating menus and start assigning pages to it. Give a url, actual files which are to be rendered (in case of static files.), in case of dynamic files, giving the file accordingly. And all this is fully server side manageable using different portlets, sort of things. So basic Roadmap is having : Areas like: Header Area - Which can contain logos, links etc. Navigation Area - Which can contains links and submenus. Content Area - Now this is where the tricky part is that that it has zones like: left, center & right. It contains Order in which it has to be displayed. So, when someday we want to change the way the articles appear on the page, we can do so easily, without any deployments. Now these zones can have n number of internal elements, like the word cloud, or the advertisement area. Footer Area: Again similar as Header Area. Currently there is a preexisting custom framework, which uses XSLT files for pulling out data from the server side. And it has the above capabilities. For example: If there's a grid it will be having a <table> tag embedded in the XSLT file. Now whatever might be the source of the data, we serialize this as XML and give it to the XSLT file and the html is derived from this and is appended to the layer in a page. The problem with this approach is: The XSLT conversion is occurring on the server side, so the server is responsible for getting the data, running XSLT transform, and append the html generated to the layer div. So, according to me, firstly this isn't the server's concern to do so. Secondly for larger applications this might be slower. Debugging isn't possible for XSLT transformation. So, whenever we face problems with data its always a bit of a trial & error method. Maintaining it is a bit of an eerie job i.e. styling changes, and other stuff. Adding dynamic values. Like JavaScript can't actually be very easily used in this. Secondly, we can't use JQuery or any other libraries with this since this is all occurring on the server. For now what I have thought about is using Templating - Javascript - JSON combination in place of XSLT, this will be offloaded to the client and the rendering will take place accordingly. This could solve the above problems and also could add mobile support for the same. Only problem which I could think of is that: It is much work and adding new portlets on the go needs to be looked into. What could be the alternatives for this? What kind of problems are there with the JavaScript approach? What are the different ways to implement the same? Are there any existing frameworks for similar usage?

• ASP.NET MVC 2 RTM Unit Tests not compiling

  - by nmarun

  I found something weird this time when it came to ASP.NET MVC 2 release. A very handful of people ‘made noise’ about the release.. at least on the asp.net blog site, usually there’s a big ‘WOOHAA… <something> is released’, kind of a thing. Hmm… but here’s the reason I’m writing this post. I’m not sure how many of you read the release notes before downloading the version.. I did, I did, I did. Now there’s a ‘Known issues’ section in the document and I’m quoting the text as is from this section: Unit test project does not contain reference to ASP.NET MVC 2 project: If the Solution Explorer window is hidden in Visual Studio, when you create a new ASP.NET MVC 2 Web application project and you select the option Yes, create a unit test project in the Create Unit Test Project dialog box, the unit test project is created but does not have a reference to the associated ASP.NET MVC 2 project. When you build the solution, Visual Studio will display compilation errors and the unit tests will not run. There are two workarounds. The first workaround is to make sure that the Solution Explorer is displayed when you create a new ASP.NET MVC 2 Web application project. If you prefer to keep Solution Explorer hidden, the second workaround is to manually add a project reference from the unit test project to the ASP.NET MVC 2 project. This definitely looks like a bug to me and see below for a visual: At the top right corner you’ll see that the Solution Explorer is set to auto hide and there’s no reference for the TestMvc2 project and that is the reason we get compilation errors without even writing a single line of code. So thanks to <VeryBigFont>ME</VeryBigFont> and <VerySmallFont>Microsoft</VerySmallFont>) , we’ve shown the world how to resolve a major issue and to live in Peace with the rest of humanity!

• Teaching high school kids ASP.NET programming

  - by dotneteer

  During the 2011 Microsoft MVP Global Summit, I have been talking to people about teaching kids ASP.NET programming. I want to work with volunteer organizations to provide kids volunteer opportunities while learning technical skills that can be applied elsewhere. The goal is to teach motivated kids enough skill to be productive with no more than 6 hours of instruction. Based on my prior teaching experience of college extension courses and involvement with high school math and science competitions, I think this is quite doable with classic ASP but a challenge with ASP.NET. I don’t want to use ASP because it does not provide a good path into the future. After some considerations, I think this is possible with ASP.NET and here are my thoughts: · Create a framework within ASP.NET for kids programming. · Use existing editor. No extra compiler and intelligence work needed. · Using a subset of C# like a scripting language. Teaches data type, expression, statements, if/for/while/switch blocks and functions. Use existing classes but no class creation and OOP. · Linear rendering model. No complicated life cycle. · Bare-metal html with some MVC style helpers for widget creation; ASP.NET control is optional. I want to teach kids to understand something and avoid black boxes as much as possible. · Use SQL for CRUD with a helper class. Again, I want to teach understanding rather than black boxes. · Provide a template to encourage clean separation of concern. · Provide a conversion utility to convert the code that uses template to ASP.NET MVC. This will allow kids with AP Computer Science knowledge to step up to ASP.NET MVC. Let me know if you have thoughts or can help.

• Entity Framework 4 mapping fragment error when adding new entity scalar

  - by Jason Morse

  I have an Entity Framework 4 model-first design. I create a first draft of my model in the designer and all was well. I compiled, generated database, etc. Later on I tried to add a string scalar (Nullable = true) to one of my existing entities and I keep getting this type of error when I compile: Error 3004: Problem in mapping fragments starting at line 569: No mapping specified for properties MyEntity.MyValue in Set MyEntities. An Entity with Key (PK) will not round-trip when: Entity is type [MyEntities.MyEntity] I keep having to manually open the EDMX file and correct the XML whenever I add scalars. Ideas on what's going on?

• Behind ASP.NET MVC Mock Objects

  - by imran_ku07

     Introduction:           I think this sentence now become very familiar to ASP.NET MVC developers that "ASP.NET MVC is designed with testability in mind". But what ASP.NET MVC team did for making applications build with ASP.NET MVC become easily testable? Understanding this is also very important because it gives you some help when designing custom classes. So in this article i will discuss some abstract classes provided by ASP.NET MVC team for the various ASP.NET intrinsic objects, including HttpContext, HttpRequest, and HttpResponse for making these objects as testable. I will also discuss that why it is hard and difficult to test ASP.NET Web Forms.      Description:           Starting from Classic ASP to ASP.NET MVC, ASP.NET Intrinsic objects is extensively used in all form of web application. They provide information about Request, Response, Server, Application and so on. But ASP.NET MVC uses these intrinsic objects in some abstract manner. The reason for this abstraction is to make your application testable. So let see the abstraction.           As we know that ASP.NET MVC uses the same runtime engine as ASP.NET Web Form uses, therefore the first receiver of the request after IIS and aspnet_filter.dll is aspnet_isapi.dll. This will start the application domain. With the application domain up and running, ASP.NET does some initialization and after some initialization it will call Application_Start if it is defined. Then the normal HTTP pipeline event handlers will be executed including both HTTP Modules and global.asax event handlers. One of the HTTP Module is registered by ASP.NET MVC is UrlRoutingModule. The purpose of this module is to match a route defined in global.asax. Every matched route must have IRouteHandler. In default case this is MvcRouteHandler which is responsible for determining the HTTP Handler which returns MvcHandler (which is derived from IHttpHandler). In simple words, Route has MvcRouteHandler which returns MvcHandler which is the IHttpHandler of current request. In between HTTP pipeline events the handler of ASP.NET MVC, MvcHandler.ProcessRequest will be executed and shown as given below,          void IHttpHandler.ProcessRequest(HttpContext context)          {                    this.ProcessRequest(context);          }          protected virtual void ProcessRequest(HttpContext context)          {                    // HttpContextWrapper inherits from HttpContextBase                    HttpContextBase ctxBase = new HttpContextWrapper(context);                    this.ProcessRequest(ctxBase);          }          protected internal virtual void ProcessRequest(HttpContextBase ctxBase)          {                    . . .          }             HttpContextBase is the base class. HttpContextWrapper inherits from HttpContextBase, which is the parent class that include information about a single HTTP request. This is what ASP.NET MVC team did, just wrap old instrinsic HttpContext into HttpContextWrapper object and provide opportunity for other framework to provide their own implementation of HttpContextBase. For example           public class MockHttpContext : HttpContextBase          {                    . . .          }                     As you can see, it is very easy to create your own HttpContext. That's what did the third party mock frameworks like TypeMock, Moq, RhinoMocks, or NMock2 to provide their own implementation of ASP.NET instrinsic objects classes.           The key point to note here is the types of ASP.NET instrinsic objects. In ASP.NET Web Form and ASP.NET MVC. For example in ASP.NET Web Form the type of Request object is HttpRequest (which is sealed) and in ASP.NET MVC the type of Request object is HttpRequestBase. This is one of the reason that makes test in ASP.NET WebForm is difficult. because their is no base class and the HttpRequest class is sealed, therefore it cannot act as a base class to others. On the other side ASP.NET MVC always uses a base class to give a chance to third parties and unit test frameworks to create thier own implementation ASP.NET instrinsic object.           Therefore we can say that in ASP.NET MVC, instrinsic objects are of type base classes (for example HttpContextBase) .Actually these base classes had it's own implementation of same interface as the intrinsic objects it abstracts. It includes only virtual members which simply throws an exception. ASP.NET MVC also provides the corresponding wrapper classes (for example, HttpRequestWrapper) which provides a concrete implementation of the base classes in the form of ASP.NET intrinsic object. Other wrapper classes may be defined by third parties in the form of a mock object for testing purpose.           So we can say that a Request object in ASP.NET MVC may be HttpRequestWrapper or may be MockRequestWrapper(assuming that MockRequestWrapper class is used for testing purpose). Here is list of ASP.NET instrinsic and their implementation in ASP.NET MVC in the form of base and wrapper classes. Base Class Wrapper Class ASP.NET Intrinsic Object Description HttpApplicationStateBase HttpApplicationStateWrapper Application HttpApplicationStateBase abstracts the intrinsic Application object HttpBrowserCapabilitiesBase HttpBrowserCapabilitiesWrapper HttpBrowserCapabilities HttpBrowserCapabilitiesBase abstracts the HttpBrowserCapabilities class HttpCachePolicyBase HttpCachePolicyWrapper HttpCachePolicy HttpCachePolicyBase abstracts the HttpCachePolicy class HttpContextBase HttpContextWrapper HttpContext HttpContextBase abstracts the intrinsic HttpContext object HttpFileCollectionBase HttpFileCollectionWrapper HttpFileCollection HttpFileCollectionBase abstracts the HttpFileCollection class HttpPostedFileBase HttpPostedFileWrapper HttpPostedFile HttpPostedFileBase abstracts the HttpPostedFile class HttpRequestBase HttpRequestWrapper Request HttpRequestBase abstracts the intrinsic Request object HttpResponseBase HttpResponseWrapper Response HttpResponseBase abstracts the intrinsic Response object HttpServerUtilityBase HttpServerUtilityWrapper Server HttpServerUtilityBase abstracts the intrinsic Server object HttpSessionStateBase HttpSessionStateWrapper Session HttpSessionStateBase abstracts the intrinsic Session object HttpStaticObjectsCollectionBase HttpStaticObjectsCollectionWrapper HttpStaticObjectsCollection HttpStaticObjectsCollectionBase abstracts the HttpStaticObjectsCollection class      Summary:           ASP.NET MVC provides a set of abstract classes for ASP.NET instrinsic objects in the form of base classes, allowing someone to create their own implementation. In addition, ASP.NET MVC also provide set of concrete classes in the form of wrapper classes. This design really makes application easier to test and even application may replace concrete implementation with thier own implementation, which makes ASP.NET MVC very flexable.

• Unique Keys not recognized by Entity Framework

  - by David Pfeffer

  I have two tables, Reports and Visualizations. Reports has a field, VisualizationID, which points to Visualization's field of the same name via a foreign key. It also has a unique key declared on the field. VisualizationID is not nullable. This means the relationship has to be 0..1 to 1, because every Reports record must have a unique, not null Visualizations record associated with it. The Entity Framework doesn't see it this way. I'm getting the following error: Error 113: Multiplicity is not valid in Role 'Report' in relationship 'FK_Reports_Visualizations'. Because the Dependent Role properties are not the key properties, the upper bound of the multiplicity of the Dependent Role must be *. What's the problem here? How can I make the EF recognize the proper relationship multiplicity?

• EF 4’s PluralizationService Class: A Singularly Impossible Plurality

  - by Ken Cox [MVP]

  Entity Framework’s new 4.0 designer does its best to generate correct plural and singular forms of object names. This magic is done through the PluralizationService Class found in the System.Data.Entity.Design.PluralizationServices namespace and in the System.Data.Entity.Design.dll assembly. [Before you ask… Yes, I’ll post my example page, the service, and the project source code as soon as my ISP makes ASP.NET 4 RTM available.

• .NET 3.5 Installation Problems in Windows 8

  - by Rick Strahl

  Windows 8 installs with .NET 4.5. A default installation of Windows 8 doesn't seem to include .NET 3.0 or 3.5, although .NET 2.0 does seem to be available by default (presumably because Windows has app dependencies on that). I ran into some pretty nasty compatibility issues regarding .NET 3.5 which I'll describe in this post. I'll preface this by saying that depending on how you install Windows 8 you may not run into these issues. In fact, it's probably a special case, but one that might be common with developer folks reading my blog. Specifically it's the install order that screwed things up for me -  installing Visual Studio before explicitly installing .NET 3.5 from Windows Features - in particular. If you install Visual Studio 2010 I highly recommend you install .NET 3.5 from Windows features BEFORE you install Visual Studio 2010 and save yourself the trouble I went through. So when I installed Windows 8, and then looked at the Windows Features to install after the fact in the Windows Feature dialog, I thought - .NET 3.5 - who needs it. I'd be happy to not have to install .NET 3.5, but unfortunately I found out quite a while after initial installation that one of my applications/tools (DevExpress's awesome CodeRush) depends on it and won't install without it. Enabling .NET 3.5 in Windows 8 If you want to run .NET 3.5 on Windows 8, don't download an installer - those installers don't work on Windows 8, and you don't need to do this because you can use the Windows Features dialog to enable .NET 3.5: And that *should* do the trick. If you do this before you install other apps that require .NET 3.5 and install a non-SP1 one version of it, you are going to have no problems. Unfortunately for me, even after I've installed the above, when I run the CodeRush installer I still get this lovely dialog: Now I double checked to see if .NET 3.5 is installed - it is, both for 32 bit and 64 bit. I went as far as creating a small .NET Console app and running it to verify that it actually runs. And it does… So naturally I thought the CodeRush installer is a little whacky. After some back and forth Alex Skorkin on Twitter pointed me in the right direction: He asked me to look in the registry for exact info on which version of .NET 3.5 is installed here: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP where I found that .NET 3.5 SP1 was installed. This is the 64 bit key which looks all correct. However, when I looked under the 32 bit node I found: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\NET Framework Setup\NDP\v3.5 Notice that the service pack number is set to 0, rather than 1 (which it was for the 64 bit install), which is what the installer requires. So to summarize: the 64 bit version is installed with SP1, the 32 bit version is not. Uhm, Ok… thanks for that! Easy to fix, you say - just install SP1. Nope, not so easy because the standalone installer doesn't work on Windows 8. I can't get either .NET 3.5 installer or the SP 1 installer to even launch. They simply start and hang (or exit immediately) without messages. I also tried to get Windows to update .NET 3.5 by checking for Windows Updates, which should pick up on the dated version of .NET 3.5 and pull down SP1, but that's also no go. Check for Updates doesn't bring down any updates for me yet. I'm sure at some random point in the future Windows will deem it necessary to update .NET 3.5 to SP1, but at this point it's not letting me coerce it to do it explicitly. How did this happen I'm not sure exactly whether this is the cause and effect, but I suspect the story goes like this: Installed Windows 8 without support for .NET 3.5 Installed Visual Studio 2010 which installs .NET 3.5 (no SP) I now had .NET 3.5 installed but without SP1. I then: Tried to install CodeRush - Error: .NET 3.5 SP1 required Enabled .NET 3.5 in Windows Features I figured enabling the .NET 3.5 Windows Features would do the trick. But still no go. Now I suspect Visual Studio installed the 32 bit version of .NET 3.5 on my machine and Windows Features detected the previous install and didn't reinstall it. This left the 32 bit install at least with no SP1 installed. How to Fix it My final solution was to completely uninstall .NET 3.5 *and* to reboot: Go to Windows Features Uncheck the .NET Framework 3.5 Restart Windows Go to Windows Features Check .NET Framework 3.5 and voila, I now have a proper installation of .NET 3.5. I tried this before but without the reboot step in between which did not work. Make sure you reboot between uninstalling and reinstalling .NET 3.5! More Problems The above fixed me right up, but in looking for a solution it seems that a lot of people are also having problems with .NET 3.5 installing properly from the Windows Features dialog. The problem there is that the feature wasn't properly loading from the installer disks or not downloading the proper components for updates. It turns out you can explicitly install Windows features using the DISM tool in Windows.dism.exe /online /enable-feature /featurename:NetFX3 /Source:f:\sources\sxs You can try this without the /Source flag first - which uses the hidden Windows installer files if you kept those. Otherwise insert the DVD or ISO and point at the path \sources\sxs path where the installer lives. This also gives you a little more information if something does go wrong.© Rick Strahl, West Wind Technologies, 2005-2012Posted in Windows  .NET   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• What are the definitive guidelines for custom Error Handling in ASP.NET MVC 3?

  - by RyanW

  The process of doing custom error handling in ASP.NET MVC (3 in this case) seems to be incredibly neglected. I've read through the various questions and answers here, on the web, help pages for various tools (like Elmah), but I feel like I've gone in a complete circle and still don't have the best solution. With your help, perhaps we can set a new standard approach for error handling. I'd like to keep things simple and not over-engineer this. Here are my goals: For Server errors/exceptions: Display debugging information in dev Display friendly error page in production Log errors and email them to administrator in production Return 500 HTTP Status Code For 404 Not Found errors: Display friendly error page Log errors and email them to administrator in production Return 404 HTTP Status Code Is there a way to meet these goals with ASP.NET MVC?

• What are the benefits of Castle Monorail 3 over ASP.Net MVC?

  - by yorch

  I have been using Castle Monorail for some years now with great success, although I haven't bothered to update the version I'm using (2 or 3 year old). Now I'm making a decision on go to ASP.Net MVC 3 or update to the latest Castle version. I have been looking documentation on the newest version of Castle projects (specially Monorail), but there is really little or no info around (I may be wrong). Does someone knows what are the benefits/new features of version 3 over ASP.Net MVC3? Thanks!

• Protocol buffer deserialization and a dynamically loaded DLL in Compact Framework

  - by cloudraven

  I saw a question related to this on the full framework here. Since it seems to have stayed unresolved for quite a while and this is for the compact framework, I though it would be better to create a new question for it. I want to deserialize types for which I am loading assemblies dynamically (with Assembly.LoadFrom) and I am getting a "Unable to identify known-type for ProtoIncludeAttribute" error. In the related question I mentioned, it was hinted that hooking AppDomain.AssemblyResolve event would help solving the problem. It makes sense for the full framework, but that event is not available in the CF. I wonder if there is a way to do this with CF. The structures I am using look a lot like this and all the classes required for deserialization are loaded from the same Assembly. If the assembly is referenced instead of dynamically loaded it works fine, but fails if done dynamically.

• Framework version used by .NET Framework 3.5

  - by bmutch

  I am trying to determine the version of the .NET framework that a dll is using. I have targeted 3.5 in my app but when I open the dll with ildasm.exe (on my dev PC with 3.5 installed), it says it is using "Metadata version: v2.0.50727" which is it really using?

• Popular .NET Compact Framework open source applications / components

  - by ollifant

  In my company I am responsible for the development of a .NET CF application which runs on top of Windows CE. We have invested much time in the development of a GUI framework, a top-level design which handles authorizations and navigation on the device, a IoC customer, ... Now I was wondering if there are any other projects which show kind of best practices (for example what the prefered way of GUI drawing is). In the following there are some which I know: UI Framework for .NET Compact Framework 3.5 Project Resistance Amplite Application Port from IPhone* Several twitter clients CaveMen from LightWorkGames* What applications / components do you know? * actually not a application, but definetely worth to take a look

• .NET platform independant sync framework

  - by Quandary

  Question: I need to synchronize a few ActionScript files from my computer to a network share (backup). I saw a quick fix would be using Microsoft Sync Framework for this, and write a windows service. My problem is I also use Linux, and before I start with MS vendor lockin, is there any sync framework/library/whatever I could use that works accross platform? Or does the MS sync framework work on Linux, too? It is my understanding that it is a wrapper around some com objects, thus it wouldn't work. All I need is synchronizing files. So never mind the database part, although it would be nice to have it, too.

• New Location for .NET 4 GAC

  - by Ricardo Peres

  .NET 4 newcomers may have realised that the old GAC location (%WINDIR%\Assembly) does not contain .NET 4 global assembly cache assemblies. Indeed, they have moved to %WINDIR%\Microsoft.NET\Assembly. It is worth noting that this folder does not use the shell extension that the older one uses, which prevents us from directly looking at the folder's contents, which, IMO, is nice (I mean, the new behavior). The old folder continues to host pre-.NET 4 assemblies.

• Entity framework entity class mapping with plain .net class

  - by Elan

  I have following in entity framework Table - Country Fields List item Country_ID Dialing_Code ISO_Alpha2 ISO_Alpha3 ISO_Full I would like to map only selected fields from this entity model to my domain class. My domain model class is public class DomainCountry { public int Country_ID { get; set; } public string Dialing_Code { get; set; } public string ISO_3166_1_Alpha_2 { get; set; } } The following will work however insert or update is not possible. In order to get insert or update we need to use ObjectSet< but it will not support in my case. IQueryable<DomainCountry> countries = context.Countries.Select( c => new DomainCountry { Country_ID = c.Country_Id, Dialing_Code = c.Dialing_Code, ISO_3166_1_Alpha_2 = c.ISO_3166_1_Alpha_2 }); It will be really fantastic could someone provide a nice solution for this. Ideally it will be kind of proxy class which will support all the futures however highly customizable i.e. only the columns we want to expose to the outer world
