• 403 Forbidden when Deploying asp.net 4.0 site to IIS 7

  - by Jordan

  So I have an EC2 instance running, the URL NoWeatherSurprises.com I have the DNS pointing there, and I set up a new site in IIS 7 and pointed it to a folder. I used Visual Studios Web Developer 2010 express to publish to this folder. It now has the binaries and such. However if I go to NoWeatherSurprises.com I get the welcome to IIS 7 screen. I'd expect to go to my application If I navigate to http://noweathersurprises.com/weather/ [weather was the folder I published to under wwwroot] I get a 403 forbidden. I have no idea why, I am guessing that it is trying to do a directory listing or something instead of launching my MVC Application. So 2 problems in summary. It is not pointing the domain to the folder directly and I need to add /weather I am getting a 403 forbidden instead of the results of my home controller with the index action. I am new to IIS 7, I had been using IIS 6 and had a lot less trouble setting it up, but I suspect that's my own fault and i am just missing something. Thanks in advance for any help

• problem with .Net xml importnode in powershell

  - by Trondh

  Hi, Im trying to construct a powershell script that uses some XML. I have a XML document where I try to add some values with email addresses. The finished xml document should have this format: (I'm only showing the relevant part of the xml here) <emailAddresses> <value>[email protected]</value> <value>[email protected]</value> <value>[email protected]</value> </emailAddresses> SO, in powershell I try to do this as a test, which fails: $newNumber = [xml] '<value>555-1215</value>' $newNode = $Request2.ImportNode($newNumber.value, $true) $emailnode.AppendChild($newNode) After some reading, I have figured out that if I do this, it suceeds: $newNumber = [xml] '<value name="flubber">555-1215</value>' $newNode = $Request2.ImportNode($newNumber.value, $true) $emailnode.AppendChild($newNode) So, I am stuck. I'm starting to wonder if I should use another function instead of importnode when I have several keys with the same name but different values. As you guys probably have figured out by now, i'm not an expert in xml. ANy help appreciated!

• Active Directory + IIS + SQL + ASP.NET

  - by Amira Elsayed Ismail

  I have sent the following question to stackoverflow website I have installed Windows server 2008 r2 on a virtual machine, Can I install Active directory with domain controller + IIS + SQL server on the same machine? I want to make web application and this web application will authenticate users from Active Directory, the web application should be published on the server IIS and the users should access it remotely from their home using domain name of my machine, Someone tell me that its very wrong to have IIS and Active directory on the same machine I got the following Answer You can't use ActiveDirectory over the internet. At least not without something like a VPN as a middle man. Their home computers will not be joined to the domain, so there is no pass-through authentication. Yes, it's a bad idea to put AD on the web server. Why is too complex to get into in an answer here. Suffice it to say that even if you did do this, it's probably would not work the way you are thinking it should. It's not impossible to do this. For instance, many of the Microsoft "Small Businesss" products put IIS, AD, and SQL Server on the same server. But, you kind of have to know what you're doing to configure it securely. Then I add the following comment Thanks for ur reply.so what you think about the best way to do this as I didn't do anything like that before should I install active directory on a machine and IIS on another machine ? and what about SQL should I add it to the same server of active directory ? I didn't mentioned also that it will be Microsoft dynamics server that will access some information about work and i have to read data from axapta also ? also what is VPN and how can I use it to let users access my web application anywhere ? Sorry for my long questions and thanks in advance so please if anyone can help I will be thankful

• ASP.NET, URL Rewriting and threads on Linux?

  - by acidzombie24

  Right now converting my normal sql(ite) syntax into compatible MS Server syntax is driving me mad. My code seems to be mono compatible judging by MoMA. However in global.asax i start several threads in Application_Start to use as a service and excessive url rewrites in Application_BeginRequest (everything is rewriting into default.aspx which calls C# code/class baded on the url). The urls do not have extensions or my have false extentions ie mysite.com/username/page/title.lol - id I need it all to go to BeginRequest. I also need files to be downloadable. Usually the path will be rewritten as from /file/user/filename to /file/u/s/user/file. Would this be supported on linux+mono+a good webserver?

• Would requiring .Net 4.0 act as a bar to adopting our software in a corporate environment?

  - by Sam

  We are developing a software product in .Net targeting large corporates. The product has both server and desktop client components. We anticipate that our product will be used by a small subset of workers in the corporation - probably those in the Finance function. We currently require .Net 3.5 but are considering moving to .Net 4. Could anyone with experience of managing IT in such an environment tell us whether requiring .Net 4.0 at this stage would be a bar to adopting our software? What attitudes prevail regarding the use of frameworks like .Net?

• Best way to set up servers for .NET performance

  - by msigman

  Assume we have 3 physical servers and let's say we are only interested in performance, and not reliability. Is it better to give each server a specific function or make them all duplicates and split the traffic between them? In other words dedicate 1 as DB server, 1 as web server, and 1 as reporting server/data warehouse, or better to put all three services on each server and use them as web farm?

• Very, very simple asp.net page takes forever to load

  - by John Hoge

  I've got a page that couldn't be more simple: <%@ Page Trace="true" %> <html> <head></head> <body> <h1>Hello World</h1> <a href="/OtherPage.aspx"/>Other Page</a> <p><%=DateTime.Now.ToString()%> </body> </html> ... but it takes forever to load. There is no database or web service call to slow it down. The trace command reveals that the time from Begin PreInot to End Render is .000049 seconds, but the page itself takes several seconds to load. It is a new web site I just created for this test, and just has a web.config & two test files. The only thing in the web.config is access control: <authorization><allow users="domain\me" /><deny users = "*"/></authorization> What else could IIS be doing with all of that time?

• Sam Abraham to Speak about MVC2 at the Florida.Net Miramar .Net User Group on July 13 2010

  - by Sam Abraham

  I am scheduled to give a presentation at the Miramar .Net User Group on July 13, 2010 about MVC and the new features in MVC2. This will be similar yet will have more advanced content since the group had already had a introduction to MVC in a previous meeting. Here is the topic and speaker bio: Sam Abraham To Speak At The LI .Net User Group on June 3rd, 2010 As you might know, I lived and worked on LI, NY for 11 years before relocating to South Florida. As I will be visiting my family who still live there in the first week of June, I couldn't resist reaching out to Dan Galvez, LI  .Net User Group Leader, and asking if he needed a speaker for June's meeting. Apparently the stars were lined up right and I am now scheduled to speak at my "home" group on June 3rd, which I am pretty excited about. Here is a brief abstract of my talk and speaker bio. What's New in MVC2 We will start by briefly reviewing the basics of the Microsoft MVC Framework. Next, we will look at the new features introduced in the latest and greatest MVC2. Many new enhancements were introduced to both the MS MVC Framework and to VS2010 to improve developers' experience and reduce development time. We will be talking about new MVC2 features such as: Model Validation, Areas and Template Helpers. We will also discuss the new built-in MVC project templates that ship with VS2010. About the Speaker Sam Abraham is a Microsoft Certified Professional (MCP) and Microsoft Certified Technology Specialist (MCTS ASP.Net 3.5) He currently lives in South Florida where he leads the West Palm Beach .Net User Group (www.fladotnet.com) and actively participates in various local .Net Community events as organizer and/or technical speaker. Sam is also an active committee member on various initiatives at the South Florida Chapter of the Project Management Institute (www.southfloridapmi.org). Sam finds his passion in leveraging latest and greatest .Net Technologies along with proven Project Management practices and methodologies to produce high quality, cost-competitive software.  Sam can be reached through his blog: http://www.geekswithblogs.net/wildturtle

• VS2012 - How to manually convert .NET Class Library to a Portable Class Library

  - by Igor Milovanovic

  The portable libraries are the  response to the growing profile fragmentation in .NET frameworks. With help of portable libraries you can share code between different runtimes without dreadful #ifdef PLATFORM statements or even worse “Add as Link” source file sharing practices. If you have an existing .net class library which you would like to reference from a different runtime (e.g. you have a .NET Framework 4.5 library which you would like to reference from a Windows Store project), you can either create a new portable class library and move the classes there or edit the existing .csproj file and change the XML directly. The following example shows how to convert a .NET Framework 4.5 library to a Portable Class Library. First Unload the Project and change the following settings in the .csproj file: <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" /> to: <Import Project="$(MSBuildExtensionsPath32)\Microsoft\Portable \$(TargetFrameworkVersion)\Microsoft.Portable.CSharp.targets" /> and add the following keys to the first property group in order to get visual studio to show the framework picker dialog: <ProjectTypeGuids>{786C830F-07A1-408B-BD7F-6EE04809D6DB}; {FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids>   After that you can select the frameworks in the Library Tab of the Portable Library:   As last step, delete any framework references from the library as you have them already referenced via the .NET Portable Subset.     [1] Cross-Platform Development with the .NET Framework - http://msdn.microsoft.com/en-us/library/gg597391.aspx [2] Framework Profiles in .NET: http://nitoprograms.blogspot.de/2012/05/framework-profiles-in-net.html

• Gems In The Visual Studio 2010 Training Kit - Introduction to ASP.NET MVC: Learning Labs

  - by Jim Duffy

  Following up on my prior “gems post” is another nugget I found in the Visual Studio 2010 and .NET Framework 4 Training Kit. ASP.NET MVC has established quite a bit of momentum in the ASP.NET development community since it was introduced in early-ish 2009 though I’m sure there are many developers who haven’t had the time or opportunity to find out what it is, not to mention learn how to use it. If you’re one of those “I’ve heard of it but I’m not sure what it really is” developers then I suggest you start your research here. Ok, back to the gem. There are a number of fantastic MVC learning resources out there including the video tutorials on the ASP.NET MVC website. Another learning resource for your journey along the yellow brick road into ASP.NET MVC land are the hands-on learning labs contained in the Visual Studio 2010 and .NET Framework 4 Training Kit. These hands-on exercises walk you through the process of creating the “M”, the “V”s, and the “C”s of ASP.NET MVC and help you gain a solid foothold into the details of creating and understanding ASP.NET MVC applications. Have a day. :-|

• AsyncBridge? Async on .NET 4.0 using VS11

  - by Alex.Davies

  I've just found something quite cool. It's a code snippet that lets you use the real VS 11 C#5 compiler to write code that uses the async and await keywords, but to target .NET 4.0. It was published by Daniel Grunwald (from SharpDevelop).That means I can stop using the Async CTP for VS2010, which is not at all supported anymore, and a pain to install if you have windows updates turned on. Obviously I couldn't ask all my users to install .NET 4.5 beta, but .NET Demon is a VS 2010 extension, so we already have .NET 4.0. At the time of writing, VS11 is in beta still, but hopefully it's stable enough for my team to use!I would have written the code myself, but I had the wrong impression that the C# 5 beta compiler only looked in mscorlib for the helper classes it needs to implement async methods. Turns out you can provide them yourself. You can get the code here: https://gist.github.com/1961087You just add it to your project, and the compiler will apparently pick it up and use it to implement async/await. I'm at my parents' place for Easter without access to a machine with VS 11 to try it out. Let me know whether you get it to work!This reminds me of LINQBridge, which let us use C# 3 LINQ, but only require .NET 2. We should stick up a webpage to explain, with a nice easy dll, put it in nuget, and call it AsyncBridge.If you were really enthusiastic, you could re-implement the skeleton of the Task Parallel Library against .NET 2 to use async/await without even requiring .NET 4. Our usage stats suggest that practically everyone that uses Red Gate tools already has .NET 4 installed though, so I don't think I'll go to the effort.

• How to reproduce System.Security.Cryptography.SHA1Managed result in Python

  - by joetyson

  Here's the deal: I'm moving a .NET website to Python. I have a database with passwords hashed using the System.Security.Cryptography.SHA1Managed utility. I'm creating the hash in .NET with the following code: string hashedPassword = Cryptographer.CreateHash("MYHasher", userInfo.Password); The MYHasher block looks like this: <add algorithmType="System.Security.Cryptography.SHA1Managed, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=blahblahblah" saltEnabled="true" type="Microsoft.Practices.EnterpriseLibrary.Security.Cryptography.HashAlgorithmProvider, Microsoft.Practices.EnterpriseLibrary.Security.Cryptography, Version=3.0.0.0, Culture=neutral, PublicKeyToken=daahblahdahdah" name="MYHasher" /> So for a given password, I get back and store in the database a 48 byte salted sha1. I assume the last 8 bytes are the salt. I have tried to reproduce the hashing process in python by doing a sha1(salt + password) and sha1(password + salt) but I'm having no luck. My question to you: How are the public keys being used? How is the password rehashed using the salt. How is the salt created? (e.g., When I say saltEnabled="true", what extra magic happens?) I need specific details that don't just reference other .NET libraries, I'm looking for the actual operational logic that happens in the blackbox. Thanks!

• WCF 3.5 to 3.0 backwards compatibility with callback services

  - by Miral

  I have a set of existing WCF services hosted in a .NET 3.0 app. They're using the WSHttp bindings and no security. I need to connect to these from a .NET 3.5 client. This seems to be working fine for the one-way services, but I also have some callback services (with CallbackContract and SessionMode = Required, using WSDualHttpBinding); these fail to connect with a timeout somewhere in the ReliableSession code. The service side cannot be changed (it's a historic version issue). Can I modify something on the client side to get this working? (I can connect with a .NET 3.0 client just fine, but I'd rather not be forced to try that path.) The open operation did not complete within the allotted timeout of 00:00:09.9410000. The time allotted to this operation may have been a portion of a longer timeout. Server stack trace: at System.ServiceModel.Channels.ReliableRequestor.ThrowTimeoutException() at System.ServiceModel.Channels.ReliableRequestor.Request(TimeSpan timeout) at System.ServiceModel.Channels.ClientReliableSession.Open(TimeSpan timeout) at System.ServiceModel.Channels.ClientReliableDuplexSessionChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout)

• Custom Event - invokation list implementation considerations

  - by M.A. Hanin

  I'm looking for some pointers on implementing Custom Events in VB.NET (Visual Studio 2008, .NET 3.5). I know that "regular" (non-custom) Events are actually Delegates, so I was thinking of using Delegates when implementing a Custom Event. On the other hand, Andrew Troelsen's "Pro VB 2008 and the .NET 3.5 Platform" book uses Collection types in all his Custom Events examples, and Microsoft's sample codes match that line of thought. So my question is: what considerations should I have when choosing one design over the other? What are the pros and cons for each design? Which of these resembles the inner-implementation of "regular" events? Below is a sample code demonstrating the two designs. Public Class SomeClass Private _SomeEventListeners As EventHandler Public Custom Event SomeEvent As EventHandler AddHandler(ByVal value As EventHandler) _SomeEventListeners = [Delegate].Combine(_SomeEventListeners, value) End AddHandler RemoveHandler(ByVal value As EventHandler) _SomeEventListeners = [Delegate].Remove(_SomeEventListeners, value) End RemoveHandler RaiseEvent(ByVal sender As Object, ByVal e As System.EventArgs) _SomeEventListeners.Invoke(sender, e) End RaiseEvent End Event Private _OtherEventListeners As New List(Of EventHandler) Public Custom Event OtherEvent As EventHandler AddHandler(ByVal value As EventHandler) _OtherEventListeners.Add(value) End AddHandler RemoveHandler(ByVal value As EventHandler) _OtherEventListeners.Remove(value) End RemoveHandler RaiseEvent(ByVal sender As Object, ByVal e As System.EventArgs) For Each handler In _OtherEventListeners handler(sender, e) Next End RaiseEvent End Event End Class

• Custom model validation of dependent properties using Data Annotations

  - by Darin Dimitrov

  Since now I've used the excellent FluentValidation library to validate my model classes. In web applications I use it in conjunction with the jquery.validate plugin to perform client side validation as well. One drawback is that much of the validation logic is repeated on the client side and is no longer centralized at a single place. For this reason I'm looking for an alternative. There are many examples out there showing the usage of data annotations to perform model validation. It looks very promising. One thing I couldn't find out is how to validate a property that depends on another property value. Let's take for example the following model: public class Event { [Required] public DateTime? StartDate { get; set; } [Required] public DateTime? EndDate { get; set; } } I would like to ensure that EndDate is greater than StartDate. I could write a custom validation attribute extending ValidationAttribute in order to perform custom validation logic. Unfortunately I couldn't find a way to obtain the model instance: public class CustomValidationAttribute : ValidationAttribute { public override bool IsValid(object value) { // value represents the property value on which this attribute is applied // but how to obtain the object instance to which this property belongs? return true; } } I found that the CustomValidationAttribute seems to do the job because it has this ValidationContext property that contains the object instance being validated. Unfortunately this attribute has been added only in .NET 4.0. So my question is: can I achieve the same functionality in .NET 3.5 SP1? UPDATE: It seems that FluentValidation already supports clientside validation and metadata in ASP.NET MVC 2. Still it would be good to know though if data annotations could be used to validate dependent properties.

• How to display NotifyIcon and SSDP Service running during AutoLogon

  - by Paul Farry

  I've got an application (that is targetting .Net Framework 2.0) that is running on startup of the System, and I'm trying to get a NotifyIcon to display. When my program starts up when a user either Runs it normally or is started as a child process after the system has already logged on everything is fine. If my application starts up as the system is performing an AutoLogon using POSReady2009 (basically XP with Single User set). Then the NotifyIcon never becomes active. If you subsequently check (in a timer) the .Visible of the Icon at any point later it always reports that it is visible = true. If you disable the SSDPSrv and restart the Computer, the Icon displays correctly. I have a sneaking suspicion this is related to .Net 3.5sp1 installed over the top of a .Net 2 system. Is there some process that I should be following to ensure that my NotifyIcon is always available to the user. I have setup RegisterWindowMessage("TaskbarCreated") but I don't get this message called, except when you forcilbly Kill Explorer.exe and restart it. Even so, a NotifyIcon interally registers for these notifications anyway, so it shouldn't be required. I'm happy to stall the startup of my program, but once the program starts up, I expect that the icon shows correctly. If there is a KB article that I cannot find detailing this I'd be happy with that too.
