Remarks
This is a MEF component part, and should be exported with the following attribute:
[Export(typeof(IWpfTextViewConnectionListener))] [ContentType("...")] [TextViewRole("...")]
Use this interface instead of IWpfTextViewCreationListener if your extension depends on the content type of the text view. This is because SubjectBuffersConnected is called when the content type of an existing buffer is changed to the appropriate content type (as well as when it is connected to the view), while TextViewCreated is called only at the creation of a text view.
