I’d like to design a class library and plan to use mutli-threading (i.e. BackgroundWorker). I will have to watch out for the thread context, from which updates are made for fields, if I plan to bind them to the GUI of the library consuming frontend. It’s not a good idea to pass the reference of the GUI dispatcher to the library, as I read. But how can I get access to the dispatcher of the application that will use the library? Is this possible?

I tried Application.Current.Dispatcher and added a reference to WindowBase (as I didn’t have the possibility to add System.Windows), but still can’t resolve the dispatcher object.

    The Application class is defined in PresentationFramework.dll. You need to reference that in order to be able to access the dispatcher through Application.Current.Dispatcher.
