Is the ASP.NET 4.0 SQL session state mechanism backward-compatible with the ASP.NET 2.0 schema for session state, or should/must we create a separate and distinct session state database for our ASP.NET 4.0 apps? I'm leaning towards the latter anyway, but the 2.0 database seems to just work, though I'm wondering if there are any substant...
I am improving the builds for an open source project which currently supports .NET Framework v2.0, v3.5, and now v4.0. Up until now, I've restricted myself to v2.0 to ensure compatibility, but with VS2010 I am interested in having real targeted builds. I'm looking for some guidance on how to edit the MSBuild csproj/sln to be able to cle...
There are a few minor places where code for my project may be able to be drastically improved if the target framework were a newer version. I'd like to be able to better leverage conditional compilation in C# to switch these as needed. Something like: #if NET40 using FooXX = Foo40; #elif NET35 using FooXX = Foo35; #else NET20 using Foo...

Are there any caveats or short comings to using the new Task API in System.Threading.Task in ASP.NET hosted under IIS? I know prior to .NET 4.0 working with any of the ThreadPool actions inside of IIS was always recommended to be avoided. ...
I used to see any .net source code (like System.String) with ReSharper and Visual Studio 2008. since I migrated to Visual studio 2010, this option doesn't give the full source code but just the definitions of the class. How can I fix this, to use the microsoft's symbols server again? Edit: Maybe the problem is only with .net-4.0 assemb...
I know from the codeing guidlines that I have read you should not do for (int i = 0; i < 5; i++) { Task.Factory.StartNew(() => Console.WriteLine(i)); } Console.ReadLine(); as it will write 5 5's, I understand that and I think i understand why it is happening. I know the solution is just to do for (int i = 0; i < 5; i++) { ...

I am pretty much interested into using the newly enhanced Parallelism features in .NET 4.0. I have also seen some possibilities of using it in F#, as much as in C#. Despite, I can only see what PLINQ has to offer with, for example, the following: var query = from c in Customers.AsParallel() where (c.Name.Contains("customer...

Hey people, I have installed VS 2010 Professional, and despite my tremendous urge to work on it since it is pleasing to the eye, it seems not to support .NET framework 3.5/3.0. Therefore, I have switched to VS 2008 rather relunctantly. Does anyone know, to add .NET framework 3.0/3.5 to the top right Combo Box within the make new pr...

I am extending the System.Net.Mail.MailAddress class to include an ID field, so I created a new custom MailAddress class that inherited from the existing class and a new custom MailAddressCollection class. I then overrode the existing System.Net.Mail.MailMessage.To to use my new collection. I would like to process the recipients in par...

I want to add usage statistics for a .NET 4.0 library I write on CodePlex. I try to follow the step described here but my problem lies with the fact that what I write is a library and not an application. One of the steps is put the Setup and Teardown attributes. I thought about adding the Setup attribute on a static constructor or a d...
Is there a free code coverage tool suitable for use with .NET 4 and NUnit that runs from the command line (and is thus suitable for use on a build server)? Please note that any tools that require editions of Visual Studio higher than Professional are not appropriate in this case. I am asking this question because I can't get NCover 1.5...
