Describe the bug

Authoring with Windows App SDK and a project reference to the component causes an error on command line build.

This is being tracked internally: task.ms/39285537

To Reproduce

1. See Add CsWinRT authoring samples WindowsAppSDK-Samples#174
2. Build pipeline error: C:\Users\cloudtest\.nuget\packages\microsoft.windowsappsdk\1.0.0\build\Microsoft.Build.Msix.Packaging.targets#L1370 C:\Users\cloudtest\.nuget\packages\microsoft.windowsappsdk\1.0.0\build\Microsoft.Build.Msix.Packaging.targets(1370,5): Error APPX1101: Payload contains two or more files with the same destination path 'WinRT.Host.Shim.dll'. Source files: D:\a\_work\1\s\Samples\CustomControls\CsApp\obj\x86\Release\net6.0-windows10.0.19041.0\win10-x86\R2R\WinRT.Host.Shim.dll C:\Users\cloudtest\.nuget\packages\microsoft.windows.cswinrt\1.6.1\lib\net5.0\WinRT.Host.Shim.dll

Current workaround is to set PublishReadyToRun to False in each pubxml file:

Will be addressed in WinAppSDK.

This was fixed in WinAppSdk 1.1.

Thanks @evelynwu-msft. @j0shuams can you confirm the samples work fine now with 1.1 and resolve this.

Yep, @angelazhangmsft confirmed when she merged her Samples PR IIRC (microsoft/WindowsAppSDK-Samples#174)

I merged in the samples with 1.1 Preview 3, but they can be updated to 1.1 GA removing the PublishReadyToRun=False workaround
