linq.compiledquery

I have the following compiled query that I want to return a list of "groups" that don't have a "GroupID" that's contained in a filtered list:

CompiledQuery.Compile(ConfigEntities contexty, List list) => from c in context.Groups where (!csList.Contains(c.GroupID)) select c).ToList()

However I'm getting the following run-time error: The specified parameter 'categories' of type 'System.Collections.Generic.List`1[[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c261364e126]]' is not valid. Only scalar parameters (such as Int32, Decimal, and Guid) are supported.

Any ideas?
