title: Removing View from Region in Silverlight PRISM
body: <p>I have a Region which can have only one active view at a time. I want to add new view to the region on user action and remove the existing view from the same region. I also want to maintain the cache of few views. If the no of view is more than the specified limit then I will remove the oldest view. Is there any direct support for it or I have to implement the Region adapter for it. Is there any other better approach for the same?</p>
