Target file for dotnet to compile .msixbundle from .NET MAUI project

Microsoft.Build.Msix.Packaging.MsixBundle.targets

<Project>

  <!--
    =======================================================================
    Microsoft.Build.Msix.Packaging.MsixBundle.targets
    =======================================================================
    
    This targets file can be imported at the bottom of the main app project file (.csproj):
    
      <Import Project="Microsoft.Build.Msix.Packaging.MsixBundle.targets" />
    
    In order to build a .msix bundle, you can use `dotnet build`:
    
      dotnet build /t:GenerateMsixBundle -f net7.0-windows10.0.19041.0 <path/to/app.csproj>
    
    In order to control the RIDs in the app bundle, you can override them using the $(RuntimeIdentifiers)
    propertyin your .csproj. Make sure to condition on the Windows TargetFramework:
    
      <PropertyGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows'">
        <RuntimeIdentifiers>win10-x64;win10-x86;win10-arm64</RuntimeIdentifiers>
      </PropertyGroup>
  -->

  <!-- Make sure all the available RIDs are specified -->
  <PropertyGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows' and '$(RuntimeIdentifiers)' == ''">
    <RuntimeIdentifiers>win10-x64;win10-x86;win10-arm64</RuntimeIdentifiers>
  </PropertyGroup>

  <!-- Make at least one RID is specified for the IDE -->
  <PropertyGroup Condition=" '$([MSBuild]::GetTargetPlatformIdentifier($(TargetFramework)))' == 'windows' and '$(RuntimeIdentifier)' == '' ">
    <_SingleProjectHostArchitecture>$([System.Runtime.InteropServices.RuntimeInformation]::OSArchitecture)</_SingleProjectHostArchitecture>
    <_SingleProjectHostArchitecture>$(_SingleProjectHostArchitecture.ToLower())</_SingleProjectHostArchitecture>
    <RuntimeIdentifier>win10-$(_SingleProjectHostArchitecture)</RuntimeIdentifier>
  </PropertyGroup>

  <!-- Workaround for https://github.com/microsoft/WindowsAppSDK/issues/3337 -->
  <PropertyGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows' and '$(RuntimeIdentifierOverride)' != ''">
    <RuntimeIdentifier>$(RuntimeIdentifierOverride)</RuntimeIdentifier>
