title: How to make my POCO classes appear in winforms DataSource list
body: <p>Let's say that I would like my binding list datasource to be typeof(Class1).</p>
  
  <p>In the properties editor, I can't see my Class1 in the datasource list.</p>
  
  <p>Is there any attribute I can decorate my class with, that will let my Class1 appear in the list ?  Something equivalent to the [DataObject] attribute in asp.Net project.</p>
  
  <p>I don't want to create a project datasource for every class.  Actually, I replace the Control.DataSource assignation in the *.Designer.cs to be of typeof(Class1) to achieve it, but It would be nice if I could choose it directly from the properties editor.</p>
