Read/write property exposing a client for this view collection.

An Object object.  

[Set] object.Client [= Object]

The Client Property syntax has these parts:

If it implements the events interface _IMcBasicViewEvents, the client automatically receives these notifications from all the views contained in the collection.

The McViews collection does NOT maintain a reference on its Client interface, so you must either: (A) Set Views.Client=Nothing before fully releasing the client interface or (B) fully release the McViews instance (which automatically does A) before fully releasing the client interface.
