What I want to achieve is this:

  • Declare a generic class (<T>),
  • Have the “T” restricted to types that implement IMySpecialInterface<X> (where “X” is not a known type),
  • And have the class inherit from a parent class.

to give an incorrect example:

public class MyClass<T> : MyParentClass where T : IMySpecialInterface<X>
{

}

What is the proper syntax to achieve this?

    You can’t use generics without knowing the types, unless you created the type at runtime.

    Your best fit would be:

    public class MyClass<T, U> : MyParentClass where T: IMySpecialInterface<U>
{

}

    UPDATE or could you potentially use dynamic?
