dotnet publish results in an error about duplicate files

[mattleibow]

Issue moved from microsoft/microsoft-ui-xaml#7845

Describe the bug

Based on this issue: dotnet/maui#9879

Passing a -r win10-x64 to a app .csproj tries to load both a "neutral" and a "RID-specific" dll/pdb into the app:

dotnet publish MyApp.csproj -c Release -f net6.0-windows10.0.19041.0 -r win10-x64

Steps to reproduce the bug

1. Clone https://github.com/mattleibow/Maui-Issue-9879
2. Execute the publish command:

   dotnet publish -r win10-x64 -f net6.0-windows10.0.19041.0 /bl .\WinUIApp\WinUIApp.csproj
   

3. Observe error:
   Failure: msbuild.binlog.zip

   error APPX1101: Payload contains two or more files with the same destination path 'MauiClassLibrary.pdb'. Source files:
   error APPX1101: ...\MauiClassLibrary\bin\Release\net6.0-windows10.0.19041.0\MauiClassLibrary.pdb 
   error APPX1101: ...\MauiClassLibrary\bin\Release\net6.0-windows10.0.19041.0\win10-x64\MauiClassLibrary.pdb 
   

4. Run build again with custom RuntimeIdentifierOverride property set:

    dotnet publish  .\WinUIApp\WinUIApp.csproj -c Release -f net6.0-windows10.0.19041.0 /p:RuntimeIdentifierOverride=win10-x86
   

5. Observe success
   Success: msbuild.binlog.zip

Expected behavior

Passing the RID should only apply the the app project, and the class library references should just be non-RID.

Additional context

I was able to make a workaround:

Add this to the bottom of the app .csproj:

<PropertyGroup Condition="'$(RuntimeIdentifierOverride)' != ''">
	<RuntimeIdentifier>$(RuntimeIdentifierOverride)</RuntimeIdentifier>
</PropertyGroup>

Then when executing, use the new property instead of the RID:

dotnet publish  .\WinUIApp\WinUIApp.csproj -c Release -f net6.0-windows10.0.19041.0 /p:RuntimeIdentifierOverride=win10-x86

It also seems that an error occurrs when PublishTrimmed set to true:

error APPX1101: Payload contains two or more files with the same destination path 'MauiApp1.pdb'. Source files:
error APPX1101: C:\Users\lopi2\source\repos\MauiApp1\MauiApp1\obj\Release\net7.0-windows10.0.19041.0\win10-x64\linked\MauiApp1.pdb
error APPX1101: C:\Users\lopi2\source\repos\MauiApp1\MauiApp1\bin\Release\net7.0-windows10.0.19041.0\win10-x64\MauiApp1.pdb

Any workaround for this? I tried making PublishTrimmed set to false but nothing solved the problem
Is this going to be solved when .NET 8 is released?

Has no effect.

  <PropertyGroup>
    <PublishTrimmed>false</PublishTrimmed>
  </PropertyGroup>
