>Both are good suggestions. Actually, one can simply add a new EntityContext to the current one only with a subset of fields and a different entity name and recompile. I have done that several times and it works fine. Of course, the first idea is straight-forward but I wanted to use the EF system here.

Hi,
Not sure what you mean by EntityContext?
Presumably not an ObjectContext since that would be overkill.
If you mean a new EntityObject then we're on the same hymn sheet - just that I find copy/paste simple.....
