We are not aware of such issues after using the Upgrade Wizard.
Could you try the following:
- Clean the project and try to rebuild it.
- Make sure that the correct assemblies are added to the project. In the case when using Implicit Styles and merging ResourceDictionaries in the App.xaml you should add references to the No.XAML assemblies.
If you still continue to experience issues could you open a support ticket and send us a runnable project that recreates the issue or a detailed steps by steps guide on how to reproduce it on our side. A short video of the issue being reproduced would also be very helpful.
