Using Fasterflect to invoke AssertWasCalled<T>(this T mock, Action<T>)

AssertWasCalled

This doesn't work - it says "No match for method with name AssertWasCalled and flags Instance | NonPublic | Public | Static on type Rhino.Mocks.RhinoMocksExtensions"

        public static void CallUsingReflection<T>(T mock, Action<T> action)
        {
            RhinoAssembly.GetType("Rhino.Mocks.RhinoMocksExtensions").CallMethod(new[] { typeof(T) }, "AssertWasCalled", new object[] { mock, action });
        }
