A listener for when a text view adapter (IVsTextView) is created and initialized that has matching roles and was created over a text data model having a matching content type. Exporters must specify at least one ContentTypeAttribute and one TextViewRole, and should mark their export using the following attribute: [Export(typeof(IVsTextViewCreationListener))], along with [ContentType] and [TextViewRole].

Remarks
Exporters must mark their export using the following attribute:
[Export(typeof(IVsTextViewCreationListener))]
You filter this listener for a specific ContentTypeAttribute and TextViewRoleAttribute.
For example, to restrict this listener to views of editable text, you would use the following attributes:
[Export(typeof(IVsTextViewCreationListener))]
[ContentType("text")]
[TextViewRole(PredefinedTextViewRoles.Editable)]
For more information about using ContentTypeAttribute and TextViewRoleAttribute, see Language Service and Editor Extension Points.
You can use this listener when you want to handle specific keystrokes in your extension. You do this by getting a reference to the text view adapter (IVsTextView) when the text view is created, then using this reference to add a command filter to a view (by using AddCommandFilter).
