I want to create a graph report which will be sourced from a one of the class in my Business Entity layer. When I try to configure data source for the report from Data Window under the .NET Objects node it does not list class in my Business Entity layer.

I am integrating this report in a .net win form project. I have a layered architecture and my business objects are in Business Entity layer and the report in Presentation layer. The presentation layer has reference to Business Entity layer.
