I remember reading something once from Microsoft that stated: “.NET 4.0 adds in-process side-by-side compatibility with earlier versions of the Framework. This feature allows an application process to simultaneously run part of its code using the .NET Common Language Runtime (CLR) 4 and other parts using older versions of the CLR.” So to answer your … Read more
I’ve discovered recently myself that there’s not a lot of online content available. Check out the Workflow Foundation 4 Resources and Community site on MSDN for some good articles and labs. Also, download the WF4 Samples. I’ve learned a lot from poking through these samples and trying things out locally. As for the WHY of … Read more
Imagine you have a method like this: bool ContainsAnX(string s) { return s.Contains(“X”); } Now, this method will always fail if you pass null to it, so you want to ensure this never happens. This is what Contract.Requires is for. It sets a precondition for the method, which must be true in order for the … Read more
Redundancy, when the first source is corrupt it gets validated or synchronized with the other.
Entity Framework 6 does support .NET 4.0. You should update your version of NuGet then try again. You can find the download at http://www.nuget.org/. I successfully downloaded EntityFramework 6.0.0-rc1 from the main nuget.org feed from an application targeting .NET 4.0

You must install the .NET Framework 4 to use these features in your application: * … Read more
Yes, there are two distinct GACs as from .NET 4.0 See here: .NET 4.0 has a new GAC, why? As stated below, the new physical location is %windir%\Microsoft.NET\assembly\ (you can interogate it using the dir command at a command prompt if you’re interested). It’s worth noting that applications running up to the 2.0 CLR will … Read more
I had a similar issue with the CultureName “UserCache”. To resolve this I deleted all the folders from in here: C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files
Parallel for loops Parallel.For(0,10,(i)=> { // Do stuff in parallel. }); The rest of the Parallel class provides some other great things like Parallel.Invoke(…) and Parallel.ForEach(…). Also, if you do anything with Linq, you can use the ParallelEnumerable.AsParallel() Method to convert your Linq queries to run in parallel. It’s all built on the Task Parallel … Read more
If you’ve got VS2010 installed, you ought to find a .NET 4.0 gacutil at C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools The 7.0A Windows SDK should have been installed alongside VS2010 – 6.0A will have been installed with VS2008, and hence won’t have .NET 4.0 support.
