Answer 1

You will most probably need to include the aspnet_Membership table that hangs off the aspnet_User table as below:

using (var dataContext = new realtydbEntities())
{
      var user =
      (
          from aspnet_Roles rol in dataContext.aspnet_Roles.Include("aspnet_Users")
          from aspnet_Users usr in rol.aspnet_Users.Include("aspnet_Membership")
          where rol.RoleId == roleID
          select usr
      );
   return user.ToList();
 }
