App instance properties cannot be accessed through App.X

Users could define an instance property on their App class but could not read or write that property from elsewhere in the project using App.PropertyName. For example, a desktop app with Property X As Integer on App should allow code in Window1 to use App.X, because App is the global application object.

Expected behaviour: after application startup, public instance properties and methods on the live App instance are accessible through App.MemberName from project code.

Actual behaviour: App.MemberName was treated only as class/shared-member access, so instance members on App were not available through the global App name.
