C# Generics and polymorphism: an oxymoron?

Question

I just want to confirm what I\'ve understood about Generics in C#. This has come up in a couple code bases I\'ve worked in where a generic base class is used to create type

Answer 1

I would prefer using abstract class to act as base of all generic types.

public abstract class SomeClass 
{
    public abstract void SomeMethod();
}

public class SomeClass : SomeClass
{
    public override void SomeMethod() { }            
}

public class DeriveFrom : SomeClass
{
    public override void SomeMethod() { base.SomeMethod(); }            
}
