Folks, I've also been trying to do exactly the same thing as Kirsten in the EF4 model designer.
I want to make an Entity which is a "view" of a few joined tables. You can easily make the entity and add scalar properties to it, but my attempts to map the properties to the underlying table columns doesn't work via any tricks I can find. Part of the problem is the understanding the cluttered mapping control, and part is the incomprehensible slew of compile errors that are generated. After all, I'm asking to do what ORM is designed to do, but I'm flummoxed as well. I'll try and find the relevant parts of Julia Lerman's book and read them again, and again. She must do this somewhere in the book. Greg
