After creating a Entity Model based on SQL Server 2008, I have to change the connection string so that queries run correctly.

I have to add...
MultipleActiveResultSets=True;

If would be nice if the Entity Developer would have this set by default just like the VS 2010 EDM designer.

Also, It would be nice to be able to modify the connection properties using the "Edit Model Setting" screen instead of having to edit the string manually in the .edps code file.
