How should I inherit IDisposable?

Question

Class names have been changed to protect the innocent.

If I have an interface named ISomeInterface. I also have classes that inherit the interface, FirstClass

Answer 1

My advice is go to the root and not directly to a concrete class. Point 2 is to the root and you are driven by some sort of contract by FirstClass. If you know that classes must implement some interface then you want to ensure that the interface they sign a contract iwth inherits IDisposable
