Does Entity Framework 4 have a Contains feature?

Question

Right now I am using an extension to linq to provide me with the functionality of Contains. I call the WhereIn like this:

Answers = Answers.WhereIn(x => x.category.catid, catSTRarray);

Is there a built in function within entity framework to use?

Answers.Where(x => catSTRarray.Contains(x.category.catid));
