Define a method with generic param of type M<T> in C#

Question

I am struggling on how to do this: I am trying to have the DoSomething method accept all classes which are derived from GenericClass < T > without having to dismantle the GenericDerived class to < GenericDerived, Base >.

class Program
{
    static void Main(string[] args)
    {
        SomeClass.DoSomething<GenericDerived>(new GenericDerived()); //Still not compiler friendly
    }
}

class Base { }

class GenericClass<T> where T : Base { }

class GenericDerived : GenericClass<Base> { }

class SomeClass
{
    public static void DoSomething<M, B>(M instance)
        where B : Base
        where M : GenericClass<B>
    {
        // Do something...
    }
}

You don't have a type parameter named T in your example. You need to add it and its constraints too.

class SomeClass
{
    public void DoSomething<M,T>(M instance) where T : Base 
                                             where M : GenericClass<T>
    {
       // Do something...
    }
}
