New Post: Reusing ViewModel with single View-Instance

Hello,

I use an MEF exported ViewModel (ReportViewModel) multiple times in my application.

<ContentControl cal:View.Model="{Binding ReportVM}" />

As expected, the same instance of the ViewModel is always used.
But It seems that caliburn always create a new View instance.
How can I prevent caliburn from creating a new View instance?

Is this possible?
