The official source of information on Managed Providers, DataSet & Entity Framework from Microsoft
We are very pleased to announce the release of Entity Framework 5. EF5 is available as the Entity Framework NuGet package and is also included in Visual Studio 2012.
EF 5 includes a number of new features and bug fixes to the EF4.3 release. Most of the new features are only available in applications targeting .NET 4.5, see the Compatibility section for more details.
The EF Designer in Visual Studio 2012 also has some new features:
The updated EF MSDN site includes a bunch of walkthroughs and videos to get you started with Entity Framework, including the new features in EF5.
You can see a list of bugs that we fixed since the EF5 RC on the EF CodePlex site.
The most notable change since RC is that new models created using the EF Designer in Visual Studio 2012 will now generate a derived DbContext and POCO classes by default. You can always revert to ObjectContext code generation if needed.
This version of the NuGet package is fully compatible with Visual Studio 2010 and Visual Studio 2012 and can be used for applications targeting .NET 4.0 and 4.5.
Some features are only available when writing an application that targets .NET 4.5. This includes enum support, spatial data types, table-valued functions and the performance improvements.
