Entity Framework 4.0 wasn't able to create auto-incremented integer identity keys with SQL Compact 3.5, which meant I had to use GUIDs instead--sort of like using a shotgun to kill a fly. Does anyone know if this problem has been fixed with the release of SQL Compact 4.0? Can I use identity keys with EF4 and SQLCE4, or am I still stuck with GUIDs? Thanks.
