Why is this Exception?- The relationship between the two objects cannot be defined because they are
- by dev-1787
I m getting this Exception-"The relationship between the two objects cannot be defined because they are attached to different ObjectContext objects."
I ve user table and country table. The countryid is referred in user table.
I am getting the above Exception when I am trying to add entry in user table.
This is my code-
using
(MyContext _db = new MyContext ())
{
User user = User .CreateUser(0, Name, address, city, 0, 0, email, zip);
Country country = _db.Country.Where("it.Id=@Id", new ObjectParameter("Id",countryId)).First();
user.Country = country;
State state = _db.State.Where("it.Id=@Id", new ObjectParameter("Id", stateId)).First();
user.State = state;
_db.AddToUser(user );//Here I am getting that Exception
_db.SaveChanges();
}
