APPX1101: Payload contains two or more files with the same destination path

[myokeeh]

Describe the bug

I'm getting APPX1101 when I have a background task referenced. See microsoft/CsWinRT#1327

I'm starting to think this could be a larger problem with WindowsAppSDK, so I'm filing an issue here.

It appears to work with a minimum subset of Nuget packages per the sample that Osirisoo0O provided, but that will not work for the intent of the background task.

Steps to reproduce the bug

1. Create an OOP background task per CsWinRT guide.
2. Add at least one of the Nuget packages below.
   CommunityToolkit.WinUI.Connectivity
CommunityToolkit.WinUI.Notifications
Microsoft.AppCenter.Analytics
Microsoft.AppCenter.Crashes
3. Build or Debug the app

Expected behavior

No errors, app runs and background task functions as it did with the UWP version.
