A few weeks ago we released EF5 Beta 1, since then we’ve been working to improve quality and polish up the release. Today we are making EF5 Beta 2 available on NuGet.
This release is licensed for use in production applications. Because it is a pre-release version of EF5 there are some limitations, see the license for more details.
Beta 2 is mainly about improving quality, here are the more notable changes since Beta 1:
Entity Framework has progressed a lot in the last 6 months and we’ve let the Power Tools fall behind. We are working on an updated version at the moment and we’re aiming to have it available in the next couple of weeks.

This version of the NuGet package is fully compatible with Visual Studio 2010 and Visual Studio 11 Beta 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. If you are targeting .NET 4.0 you still get all the bug fixes and other minor improvements.
We are seeing a lot of great Entity Framework questions (and answers) from the community on Stack Overflow. As a result, our team is going to spend more time reading and answering questions posted on Stack Overflow.
We would encourage you to post questions on Stack Overflow using the entity-framework tag. We will also continue to monitor the Entity Framework forum.
