Describe the bug
Starting from version 7.3.2511061 of the Xbox Game Bar NuGet package, there is a new type added: Microsoft.Gaming.XboxGameBar.Private.IXboxGameBarWidgetHost10. However, according to the readme.txt file in the package, it has the same InterfaceId as Microsoft.Gaming.XboxGameBar.Private.IXboxGameBarWidgetHost9: BC40A15A-6961-4D04-A9CD-34680A0F5ACD.
When copied over to the package.appxmanifest file of the project as instructed, this starts causing a crash in Visual Studio 2026 XAML designer, where the duplicated InterfaceId is referenced.
To Reproduce
Copy over required XML from readme.txt of the package to the package.appxmanifest file of your project. Visual Studio XAML designer will not work anymore.
Expected behavior
Unique InterfaceId for each type and no crashes for VS XAML designer.
Screenshots
