I have a navigation plugin which I want to extend to allow support for context navigation. I've got everything I need except for the NavigationOptions instance. In my INavigateFromHereProvider I get called with an IDataContext so can create the NavigationOptions from this using the NavigationOptions.FromDataContext method. Great.
In my context action I don't get called with a IDataContext, I get given a ICSharpContextActionDataProvider during construction. I can get my IDeclaredElement from this to base my navigation decision on, but I'm not sure how to create my NavigationOptions instance. It feels like I should be using NavigationOptions.FromWindowContext but I seems to need a PopupWindowContextSource and I don't know where to get one of these from.
So where can I get a relevant PopupWindowContextSource to create my NavigationOptions from?
