AFAIK the NpgSQL .Net data provier does not support IDE integration but ODBC should. So it is more difficult to establish a strong typed database access. But indeed some third party .Net data providers support IDE integration. They may be an option for me. Please correct me if I am wrong with the things I wrote above.
