Question

Model:
public class Address
{
[Key]
public long AddressId { get; set; }
public string Street { get; set; }
public string Town { get; set; }
public string State { get; set; }
public string Country { get; set; }
}
public class User
{
[Key]
public long UserId { get; set; }
public string UserName { get; set; }
public string Password { get; set; }
public virtual List<Address> Addresses { get; set; }
}
DBContext:
public class DataModelContext : DbContext
{
public DbSet<Address> Addresses { get; set; }
public DbSet<User> Users{ get; set; }
}
Using above code its creating this schema for DB.
Addresses Users
----------- -------
AddressId(PK) UserId(PK)
Street UserName
Town Password
State
Country
User_UserId(FK)
Now i want to access User_UserId from Addresses table, but it not showing any property there. Its giving error "Address does not contain a definition for User_UserId.....
using (var db = new DataModelContext())
{
db.Addresses.Select(x=>x.User_UserId).ToList();
}

Answer 1

Use Foreign-Key Association instead of independant association while creating models. It means that, you must include a foreign key property in your model alongside with a corresponding Navigational Property. For example:
public class Address
{
...
public int UserId {get; set;} //Foreign-Key property
[ForeignKey("UserId")]
public virtual User User { get; set; } // Navigational Property
...
}
