Doesn't work with object of derived class

[NaveenkumarIyappan]

The comparer doesn't work when object of derived class is used. Ex:

public class BaseClass
{
 public int Id {get; set;}
}

public class DerviedClass
{
 public string Name {get; set;}
}

Comparer works when BaseClass property is different

var obj1 = new DerivedClass { Id = 1, Name = Foo };
var  obj2 = new DerivedClass { Id = 2, Name = Foo };

var _comparer = new ObjectsComparer.Comparer<BaseClass>();
var equal = _comparer.Compare(obj1, obj2, out differencesList);
// equal is false

But when derived class property is different it doesn't

var obj1 = new DerivedClass { Id = 1, Name = Hello };
var  obj2 = new DerivedClass { Id = 1, Name = Foo };

var _comparer = new ObjectsComparer.Comparer<BaseClass>();
var equal = _comparer.Compare(obj1, obj2, out differencesList);
// equal is true

Is this a issue of it's by design?

I think you have to write it like this:

var _comparer = new ObjectsComparer.Comparer<DerivedClass>();

@reponemec is right. When you do Comparer() only members of T will be compared
