I have a Class in my main WPF application which has a Property defined in the class as follows:
Public Class AppExample
Public PropertyName As CollectionViewSource
The project solution also inherits a Class Library (separate project but included in the solution and using the Inherits statement) - in the Class Library I want to do the same thing but I get an error.
Public Class ClassLibraryExample
Public PropertyName as CollectionViewSource
this results in:
Type 'CollectionViewSource' is not defined
How do I fix this?

When you are using CollectionViewSource you have to use Data namespace(System.Windows.Data).
