Entity Framework 4.1 Code First approach to create many-to-many relation?

I think problem here lies in the WCF RIA service, not anything EF related. That is, that WCF doesn't like interfaces. Solution would be use Collection instead of ICollection .

I'm sure EF won't mind it and it will fix your WCF problem.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
