it helps some times I got the solution for this problem, we can call it by using reflection as mentioned below:
code :
xDerived2 child = new xDerived2();

            Action parentPrint = (Action)Activator.CreateInstance(typeof(Action), child, typeof(xDerived1).GetMethod("myMethod").MethodHandle.GetFunctionPointer());
            parentPrint.Invoke();

I wish this help you i have seen many posts that describe how to call base class function is called inside a derived class function using the super keyword.I want to call a base class overloaded function globally using a derived class object. , Input:
code :
objb = b()
super(b, objb).fun()
fun in base class

help you fix your problem Your code already works, so I don't know what the question is.
However, one thing I will say is that there's a standard way to handle control flow like this, without resorting to method meta-programming: yield. You can do something like this:
code :
class Parent
  def common_logic(params)
    # Some common code which it's Child classes share
    yield
  end
end

class Child < Parent
  def child_method(params)
    # ...
  end

  def some_other_method(params)
    common_logic(params) { child_method(params) }
  end
end

To fix this issue You would need to construct an object of type A. You have overridden method m1 in the derived class, and so any calls to m1 on an object that was created as a B will have the B version of m1 invoked. Without using super, there's no way to instruct the compiler to make the non-virtual call to the base-class version.

Any of those help You need to stub out MyChildClass instead of the abstract class. This worked for me.
