.net-4.0

Using VS 2010 beta 2, ASP.NET MVC.

I tried to create an Entity framework file and got the data from my database.

There were some issues with the relationships, so I started to tweak things around, but I kept getting the following error for simple one-to-one relationships

Error   1	Error 113: Multiplicity is not valid in Role 'UserProfile' in relationship 'FK_UserProfiles_Users'. 
Because the Dependent Role properties are not the key properties, the upper bound of the multiplicity of the Dependent Role must be *.  myEntities.edmx	2024

My Users table is consists of some other many-to-many relationships to other tables, but when I try to make a one-to-one relationship with other tables, that error pops up.

Users Table

UserID
Username
Email

etc..

UserProfiles Table

UserProfileID
UserID (FK for Users Table)
Location
Birthday
