Telerik Report doesnt see referenced classes/methods

I have static classes which has the DAL methods which I want to use in my Telerik Report
To do that I drag an objectDataSource to my report and none of those classes I referenced show up in Configure Object Data Source wizard.
Here is a quick solution:
Just add a public struct like  this to each one of your static class , recompile DAL and Telerik now will see your methods

        public struct  ShowMyClass{};
