When I run my program (which is an add-in for Visual Studio) in Visual Studio 2010, in a wpf application, it opens every .xaml document which is an item of the wpf application.
It will be very boring problem if my application would have a lot of .xaml files.
I think it has something to do with the BackgroundWorker class.
