I am trying to continue developing a Visual Studio C# Express project in Blend 3.

In this existing project in Window1.xaml.cs I have a Window\_Loaded method.  
In this method I have instantiated an object called EditBuffer and then set the DataContext of the window to EditBuffer.

EditBuffer takes two custom types as parameters but there is a also an empty constructor.

EditBuffer has various public dependency properties and freezable collections which I would like to bind a GUI to.

How do I add this existing object, EditBuffer, as a data source in Blend 3?

Please, can this be done?
