Because you need an instance and not just a method call you yaşama't let the generic type be inferred by the compiler (see this discussion) but have to do so when creating the instance:

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).
