Entity Framework and Framework 4.1
I came across this article about new features of Entity Framework, coming with Framework 4.1.The ADO.NET Entity Framework 4.1 was released back in April and includes a series of new features that build on top of the existing Entity Framework 4 functionality that was released in the Microsoft .NET Framework 4 and Visual Studio 2010.The Entity Framework 4.1 is available as a standalone installer (msdn.microsoft.com/data/ee712906), as the “EntityFramework” NuGet package and is also included when you install ASP.NET MVC 3.01.
