Upon deployment of  one of our maintain software http://www.pentaclesinc.com/moving_pro.asp?disp=1 , we stuble on System.Data.EntityCommandExecutionException.   Only to find out that one of our users are using SQL 2000 in which I believe the multiple result set are not supported. So to solve the issue we  modify the .EDMX file with a text editor and change the
ProviderManifestToken="2000"
