Using EF 4 on .NET 3.5 SP1
Is it possible to use Entity Framework v4.0 in a .NET 3.5 application? I mean, can i just reference the related assemblies for EF 4.0 and use it in my .NET 3.5 application?
Thanks.

No, the EF 4.0 uses the .NET 4.0 framework, which is newer and completely separate from the .NET 3.5 framework.
