I'm been looking around and trying to see if the Entity Framework 4 will run under Visual Studio 2008, but can;t find any references to it.
Can you get EF4 working on VS2008?

A:
On the ADO.NET Entity Framework Team blog, they have stated the the EF 4 is explicitly targeted for .NET4 and Visual Studio 2010.
So, I would say no, it's not possible.
