I have Visual Studio 2008 and 2010 (both Professional editions) installed. I installed Entity Framework 4.1 but after that neither VS-2008 nor VS-2010 is showing ADO.NET Entity Data Model in the choices when I select Add New Item from the Solution Explorer.

I tried Maintenance option of the Setup and re-installed VS 2010, but still EF is unavailable, whereas it is being listed in Windows uninstall programs list. I even tried installing NuGet package, but still it is unavailable.

How to resolve this conflict?

Make sure you have set your Target framework to .net 3.5 SP1+.

Also, Install Visual Studio 2008 Service Pack 1, since I've seen people not being able to see the ADO.NET Entity Data Model because they have not installed VS2008 SP1.

  • I am using Visual Studio 2010 and the Target Framework is set to .NET 4.0. Uninstalling VS from G: partition (Win 7 is installed here) and re-installing to C. Few guys suggested me that template files are lost if VS is installed other than C partition. – RKh Oct 02 '11 at 10:07
