Question

No foreign keys defined in the database. So I’ve setup associations.

problem: can’t seem to be able to reference the Role table as expected:

I can get as far as u.UserNamesInRole then can’t make the jump to role table.

IEnumerable<fmwebapp1.Old_App_Code.TelerikUsersDataContext.User> userList = (from u in dbTelerik.Users
where u.UsersInRoles.Role.Name = "admin"
select u.UsersInRoles);

In a many-to-many relationship, when I want results from one side only, filtered by values on the other side, I usually start my query in the middle of the relation:

To get a role’s users:

var users = from ur in context.UsersInRole
            where ur.Role.Name == "admin"
            select ur.User;

To get a user’s roles:

var roles = from ur in context.UsersInRole
            where ur.User.UserName == "Jon"
            select ur.Role
