  • Revisiting .NET, but what should I focus on?

    - by Wayne M
    After about a two-year hiatus, I'm brushing up on my .NET skills to find a .NET job (my previous two positions have very little development, or development using legacy technologies, so apart from a few very minor apps I have not touched .NET in close to two years). I'm aware of things like ASP.NET MVC, and I have previously read on things like NHibernate and DI/IOC, albeit I have yet to use them apart from very trivial "Hello World" type applications. I have a subscription to Rob Conery's Tekpub website and occasionally watch these videos when I have free time. My concern is this: I don't live in a very technical area. I would be surprised if any but the most tech-savvy companies have heard of, let alone use, ASP.NET MVC, NHibernate (or even LINQ/EF), or know about IoC. I would be willing to bet a large sum of money that 95% of the possible jobs I could obtain will use the following: Visual Source Safe, if any VCS at all ASP.NET 2.0 Webforms (3.5 if lucky) Raw ADO.NET on top of a very thin implementation of the Gateway pattern Stored Procedures in the database for most CRUD operations Gratuitous use of code-behind, with a Service layer if I'm lucky If I were extremely lucky, I might find a shop that has heard of ORMs and either uses one, or has wrote their own data abstraction. Also if I were lucky, the company would be using Model-View-Presenter. In light of this I'm not sure what I should focus on learning. Personally, I would prefer to be using the latest stuff - ASP.NET MVC, NHibernate, jQuery, WCF etc. Reality says I should go back to the basics, since it looks like most potential opportunities aren't going to be anywhere near the cutting edge, or anywhere close to it. And, as much as I would like to find a position and start to show the other developers the benefits, in my past experience this has usually resulted in my being fired for "not being a team player" and doing things the bad old way. So, I am curious how you would approach a situation like this? What should I focus on, in order to A) Reaquaint myself with .NET, and B) Prepare myself to obtain a .NET job again that is more than likely going to use techniques that I and most other knowledgeable developers will scoff at?

  • .NET / WPF Alternative

    - by eWolf
    I know the .NET framework and WPF pretty well, but I think the whole thing has gotten too blown up, especially for small apps as the whole .NET framework 3.5 weighs 197 MB by now. I am looking for a language/framework/library that provides functionality similar to that of WPF (animations, gradients, a.s.o.) and the .NET framework (of course not everything, but the basic features) and which is faster and more lightweight than the .NET framework and creates smaller and faster applications than the ones using .NET. Do you have any suggestions?

  • Thoughts on streamlining multiple .Net apps

    - by John Virgolino
    We have a series of ASP.Net applications that have been written over the course of 8 years. Mostly in the first 3-4 years. They have been running quite well with little maintenance, but new functionality is being requested and we are running into IDE and platform issues. The apps were written in .Net 1.x and 2.x and run in separate spaces but are presented as a single suite of applications which use a common navigation toolbar (implemented as a user control). Every time we want to add something to a menu in the nav we have to modify it in all the apps which is a pain. Also, the various versions of Crystal reports and that we used tables to organize the visual elements and we end up with a mess, especially with all the multi-platform .Net versions running. We need to streamline the suite of apps and make it easier to add on new apps without a hassle. We also need to bring all these apps under one .Net platform and IDE. In addition, there is a WordPress blog styled to match the style of the application suite "integrated" into the UI and a link to a MediaWiki Wiki application as well. My current thinking is to use an open source content management system (CMS) like Joomla (PHP based unfortunately, but it works well) as the user interface framework for style templating and menu management. Joomla's article management would allow us to migrate the Wiki content into articles which could be published without interfering with the .Net apps. Then essentially use an IFrame within an "article" to "host" the .Net application, then... Upgrade the .Net apps to VS2010, strip out all the common header/footer controls and migrate the styles to use the style sheets used in the CMS. As I write this, I certainly realize this is a lot of work and there are optimization issues which this may cause as well as using IFrames seems a bit like cheating and I've read about issues with IFrames. I know that we could use .Net application styling, but it seems like a lot more work (not sure really). Also, the use of a CMS to handle the blog and wiki also seems appealing, unless there is a .Net CMS out there that can handle all of these requirements. Given this information, I am looking to know if I am totally going in the wrong direction? We tried to use open source and integrate it over time, but not this has become hard to maintain. Am I not aware of some technology out there that will meet our requirements? Did we do this right and should we just focus on getting the .Net streamlined? I understand that no matter what we do, it's going to be a lot of work. The communities considerable experience would be helpful. Thanks!! PS - A complete rewrite is not an option.

  • Is ASP.NET MVC 2 Bin-deployable?

    - by Nevada
    I know that ASP.NET MVC 1.0 is bin-deployable as explained in Phil Haack's article. Is ASP.NET MVC 2.0 also bin-deployable? Has anyone done this already that can point out potential pitfalls specific to version 2.0 if there are any? I would like to deploy a relatively simple ASP.NET MVC 2.0 onto a Windows 2008 Web server that does not have ASP.NET MVC 2.0 installed. It is running .NET Framework 3.5 Service Pack 1. Thanks!

  • About Backward Compatibility of .NET Framework 4

    - by wuminqi
    We have an WPF Application build on .net framework 3.5. Some testers find if they uninstall .net framework 3.5, but install .net framework 4.0, our APP fails to launch itself. Dose this mean that .net framework 4.0 does not include all 3.5 libs, and users have to install .net 3.5 even though they have 4.0? I see here are some migration issues listed by Microsoft http://msdn.microsoft.com/en-us/library/ee941656.aspx#windows_presentation_foundation_wpf Are they all breaking changes so that the backward compatibility is ruined? Thanks

  • IIS 6 Windows Authentication in ASP.Net app fails

    - by Kjensen
    I am trying to install an ASP.Net app on an IIS6 webserver. The site requires the user to authenticate with windows, and this works on several other apps on the same server. In IIS I have enabled anonymous access and windows authentication. In web.config, authentication is set to: <authentication mode="Windows"/> and authorization...: <authorization> <allow roles="Users"/> <deny users="*"/> </authorization> Ie. allow all users in role "Users" and deny everybody else. This is the approach that is working with several other apps on the same server. If I run the site, I am prompted for username and password. If I remove the line: <deny users="*"/> I can access the site and everything works - but the user credentials are not passed to the site (Page.User.Identity.Name returns a blank string in ASP.Net). The site has identical (inherited) file permissions as other working sites on the server. The only difference in authentication/authorization between this site and the other working sites is, that this runs Asp.Net 4 (but there are other working asp.net 4 sites on the server as well). What am I missing here? Where should I look?

  • What does 'useLegacyV2RuntimeActivationPolicy' do in the .NET 4 config?

    - by Cameron MacFarland
    While converting a project that used SlimDX, and therefore has unmanaged code, to .NET 4.0 I ran into the following error: Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information. Googling around gave me the solution, which is to add this to the applications config: <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup> </configuration> My question is, what is the useLegacyV2RuntimeActivationPolicy doing? I can't find any documentation about it.

  • How to update model in the database, from asp.net MVC2, using Entity Framework?

    - by Eedoh
    Hello. I'm building ASP.NET MVC2 application, and using Entity Framework as ORM. I am having troubles updating object in the database. Every time I try entity.SaveChanges(), EF inserts new line in the table, regardless of do I want update, or insert to be done. I tried attaching (like in this next example) object to entity, but then I got {"An object with a null EntityKey value cannot be attached to an object context."} Here's my simple function for inserts and updates (it's not really about vehicles, but it's simpler to explain like this, although I don't think that this effects answers at all)... public static void InsertOrUpdateCar(this Vehicles entity, Cars car) { if (car.Id == 0 || car.Id == null) { entity.Cars.AddObject(car); } else { entity.Attach(car); } entitet.SaveChanges(); } I even tried using AttachTo("Cars", car), but I got the same exception. Anyone has experience with this?

  • Which datagrid to use for ASP.NET MVC2 project?

    - by Nick
    Hi, I am developing a commercial MVC2 app that requires a grid that has callback update in some form to support 10,000+ rows. It should also support relatively rich content (icons, multiline descriptions etc). Although it requires the usual paging/scrolling/sorting features it does not need support for grouping. So nothing that special. The commercial grids I looked at were Component Art (http://www.componentart.com/products/aspnetmvc/datagrid/) and Telerik (http://www.telerik.com/products/aspnet-mvc/grid.aspx) which both look pretty good but may be a little OTT for what I need. They are also $800 and $999 respectively (1 developer). I've also looked at jqGrid (http://www.trirand.net/download.aspx) and the grid from MvcContrib. These appear ok but for a commercial app I am concerned that these may be risky options - though could be wrong there. I'd really appreciate any views/exprience on either the above grids or perhaps you can suggest a better option/approach. FYI I am using EF4 and C#. Cheers

  • ASP.NET MVC:Why does the CheckBoxFor render an additional input tag and how can I get the value usin

    - by Nikron
    Hi, In my ASP.NET MVC app I am rendering out a checkbox using the following code: <%= Html.CheckBoxFor(i=>i.ReceiveRSVPNotifications) %> Now I see that this renders both the checkbox input tag and a hidden input tag. The problem that I am having is when I try retrieve the value from the checkbox using the FormCollection: FormValues["ReceiveRSVPNotifications"] I get the value "true,false". When looking at the rendered out HTML I can see the following: <input id="ReceiveRSVPNotifications" name="ReceiveRSVPNotifications" value="true" type="checkbox"> <input name="ReceiveRSVPNotifications" value="false" type="hidden"> So the FormValues collection seems to join these two values since they have the same name. Any Ideas?

  • TryUpdateModel is not working for new Record on ASP.NET MVC Page?

    - by Rita
    Hi I have a customer Registartion page using ASP.NET MVC with fields like FirstName, LastName, Address from AddressDetail Table. When i create a new object for CustomerMaster and trying to update the fields using TryUpdateModel, it is not updating. But the TryUpdateModel is working fine on the Edit Profile Page and that particular record is referenced. CODE on Registartion Page: AddressDetail add = new AddressDetail(); bool status = TryUpdateModel<AddressDetail>(add, "addr", new[] { "FirstName", "LastName", "Address_1", "Address_2", "ZipCode", "City", "Phone", "Fax" }, formData); CODE on Edit Profile Page: AddressDetail addr = (from a in miEntity.AddressDetail where a.AD_Id == 20 select a).First(); bool rc = TryUpdateModel<AddressDetail>(addr, "addr", new[] { "FirstName", "LastName", "Address_1", "Address_2", "ZipCode", "City", "Phone", "Fax" }, formData); Does anybody run into same issue with TryUpdateModel? Doesn't it update the Model for New Record? Thanks

  • WCF Data Services consuming data from EF based repository

    - by John Kattenhorn
    We have an existing repository which is based on EF4 / POCO and is working well. We want to add a service layer using WCF Data Services and looking for some best practice advice. So far we have developed a class which has a IQueryable property and the getter triggers the repository 'get all users' method. The problem so far have been two-fold: 1) It required us to decorate the ID field of the poco object to tell data service what field was the id. This now means that our POCO object is not 'pure'. 2) It cannot figure out the relationships between the objects (which is obvious i guess). I've now stopped this approach and i'm thinking that maybe we should expose the OBjectContext from the repository and use more 'automatic' functionality of EF. Has anybody got any advice or examples of using the repository pattern with WCF Data Services ?

  • wcf data service security configuration

    - by Daniel Pratt
    I'm in the process of setting up a WCF Data Services web service and I'm trying to sort out the security configuration. Although there's quite a lot of documentation out there for configuring WCF security, a lot of it seems to be outmoded or does not apply to my scenario. Ultimately, I am planning on managing authorization of operations via change interceptors. Thus, all I really need is the simplest way to permit a client to pass credentials along with a request and to be able to authenticate those credentials against either AD or an ASP.NET membership provider (I'd much prefer the latter unless it makes things much more complicated). I'm intending to manage encryption at the transport level (i.e. HTTPS). I'm hoping that the eventual solution does not involve a huge web.config. Likewise, I'd much prefer to avoid writing custom code for the purpose of authentication.

  • Parameter parsing with Java Restlet

    - by Leaf
    I'm trying to make a calculator web service that has more than 10 parameters. Is there any function in the Java Restlet or in Java itself that allows you to see the parameter ids? e.g. http://mywebsite.com/calculator?id1=value1&id2=value2&id3=value3 = I'm trying to access the values of id1, id2, and id3 so that I don't have to require people using the web service to input all parameters (some of them are likely to be 0).

  • Test data generators / quickest route to generating solid, non-repetitive, but not-real database sam

    - by Jamo
    I need to build a quick feasibility test / proof-of-concept of a remote database for a client, that will be populated with mostly-typical Company and People data (names, addresses, etc); 150K records or so. The sample databases mentioned here were helpful: http://stackoverflow.com/questions/57068/good-databases-with-sample-data ...but, I'd like to be able to generate sample data like this easily on less-typical datasets as well. Anyone have any recommendations for off-the-shelf (or off-the-web) solutions?

  • Max TCP Connections to a machine

    - by A9S6
    I am creating a Windows Service in .NET to which N number of client can connect. The service starts a TCP listener and accepts the client connections. The problem I am facing is that I can only open 10 connections to this service. The listener::AcceptTcpClient() method accepts only 10 connection and throws an exception for 11th one. The client application uses the System.Net.Sockets.TcpClient class and the service is using System.Net.Sockets.TcpListener class. This is the exception that I am getting when I try to make a number of connections in a for loop to this service (after the 10th connection is made): "Unable to read data from Transport connection: An exsting connection was forcibly closed by remote host"

  • Resources related to data-mining and gaming on social networks

    - by darren
    Hi all I'm interested in the problem of patterning mining among players of social networking games. For example detecting cheaters of a game, given a company's user database. So far I have been following the usual recipe for a data mining project: construct a data warehouse that aggregates significant information select a classifier, and train it with a subsectio of records from the warehouse validate classifier with another test set lather, rinse, repeat Surprisingly, I've found very little in this area regarding literature, best practices, etc. I am hoping to crowdsource the information gathering problem here. Specifically what I'm looking for: What classifiers have worked will for this type of pattern mining (it seems highly temporal, users playing games, users receiving rewards, users transferring prizes etc). Are there any highly agreed upon attributes specific to social networking / gaming data? What is a practical amount of information that should be considered? One problem I've run into is data overload, where queries and data cleansing may take days to complete. Related to point above, what hardware resources are required to produce results? I've found it difficult to estimate the amount of computing power I will require for production use. It has become apparent that a white box in the corner does not have enough horse-power for such a project. Are companies generally resorting to cloud solutions? Are they buying clusters? Basically, any resources (theoretical, academic, or practical) about implementing a social networking / gaming pattern-mining program would be very much appreciated. Thanks.
