I recommend that you not return Entities directly. Unfortunately, Microsoft chose to include implementation-specific data as part of the DataContract for entities. This will not interoperate with other platforms, and is the sort of thing that might fail to interoperate even between .NET versions.

Instead, I recommend you follow the Data Transfer Object pattern and just return POCO classes that are copies of the data in the entities, with no behavior. You can return List of such classes to represent a table, etc.
