MVC 3 "parameterless constructor defined for this object."

While working on my MVC 3.0 project i got this shocking error when i put my grid and a BeginForm() on the same page while i was passing a List of my model to the View. so here are some steps that i do and get it fixed.

1. Add and empty constructor to your Model

public class MyModel

    {

         ////Constructor of MyModel Class

              public MyModel()

                 {

                  }

        /// End constructor

    }
