Error I don't understand
Please help me with this error...
I'm making the relationships between database tables, and there is a relation between a table i created "UserDetails" and the "aspnet_Membership" table where the UserID in (UserDetails) is a primary key and it's a foreign key in (asp_Membership).
But when I want to save this I get this error:
Unable to create relationship 'FK_aspnet_Membership_UserDetails'.
The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_aspnet_Membership_UserDetails". The conflict occurred in database "C:\USERS\RUBA\DOCUMENTS\VISUAL STUDIO 2010\PROJECTS\PROJECT1\FIRST\SITE\APP_DATA\ASPNETD B.MDF", table "dbo.UserDetails", column 'UserID'.
