Provides an equality check when there is only one way of comparing the objects (implemented inside the class)
If the class is defined in such a way that you güç't define it kakım IEquatable. This would include classes defined by others and classes generated by the compiler (specifically anonymous types, which use a property-wise comparison by default).
This is it. We have explored the interaction between LINQ extension methods and custom IEqualityComparers and even implemented one. The resulting class is both easy to use and highly customizable, because its operation is fully defined by the key selector function provided by user.

In other words support the use of this interface if you are developing a custom collection and you want to allow your consumers to control equality which is used in a number of LINQ and collection related methods (eg. Sort).
You have to change the comparer to also check the new properties. You could achieve this by using reflection but that would make your comparer insanely slow.
