Question

How can I add bool Equals(object obj) method to class that is created automatically (in my case by edmx model).

One solution that I mean is to inherit this class and use this new class, but I’m looking for something different.

Answer 1

The class is partial, so you can create a new partial class.

public partial class MyClass
{
  bool Equals(object obj)
  {
    // code here
  }
}
