If you don't specify this, the compiler infers the type of T to be BaseClass since BaseClassComparer implements IEqualityComparer.

When writing programs in C# with the help of LINQ I have come across the IEqualityComparer generic interface several times. The name conveys the purpose of the interface clearly, still, surprisingly, my first attempts to apply it were marked by strong confusion - the thing merely didn't work the way I wanted it to.

IEqualityComparer is an interface for an object that performs the comparison on two objects of the type T.

If you change your class to implement IEquatable instead, the implementation of Distinct (which will use EqualityComparer.Default which in turn sees your type implements IEquatable and delegates to that) will work birli you expect.

(Making matters worse, there is a typo in the spec that says that "choose the more specific" is the right thing to do!
