What's the difference between IEquatable and just overriding Object.Equals()?
...
That is true in C++ but not .NET languages which enforce type safety. There is a runtime cast and if the cast does not succeed, an exception is thrown. So there is a small runtime penalty to pay for casting. The compiler can optimize away up...
