Is there any way to use Entity Framework 4.1 code First approach using Visual Studio 2008 Service Pack 1?

I googled a lot but didn't get any answer.开发者_开发技巧

I have used EF 4.1 feature in vs 2010 with MVC and N tier application. But There is a need for me to use Entity Framework 4.1 Code first approach in Visual Studio 2008 service pack 1 . Because my application has built in .net Framework 3.5 .

It is not possible. EntityFramework.dll has dependency on System.Data.Entities.dll from .NET 4.0.
