When a user has multiple instances of my WPF app saved in a workspace, I'd like the app to save app data such as say a currency pair in focus or a radio button selected to be saved per instance of the app, so that when the workspace is opened each app is restored to the state the user saved it in. Could IAppHost.PreferencesStore or IAppHost.Storage services provide the solution here? Does either of these services save the app data per instance of the app? Or do both of these services not distinguish which instance of the app saves the data?
