How to call a static method form interface in a generic class.

So I have a class as bellow.

public interface ISetup<T, P> where T : class {
    public static T /*.*/ Setup(T target, P args) {
        return target;
    }
}

public interface ISetup<T, P> where T : class {
    public static T /*.*/ Setup(T target, P args) {
        return target;
    }
}

and then a second generic class.

public class ClassName<T, P> where T : class, ISetup<T, P>, new() {
    public T MethodName(P setupArg) {
        var holder = new T();
        return ISetup<T, P>.Setup(holder, setupArg);
    }
}

public class ClassName<T, P> where T : class, ISetup<T, P>, new() {
    public T MethodName(P setupArg) {
        var holder = new T();
        return ISetup<T, P>.Setup(holder, setupArg);
    }
}

but I am getting the error.

The problem is I can't directly call the type from a generic. Is there anyway to do this, or am I trying to do something C# just can't do?
