ConsoleApp21.zip

use above asset. In commandline run dotnet publish -r win-x64. Get error:

@ujjwalchadha this may not be a CsWinRT issue - William is following up with more investigation

This looks like a bug in the .NET SDK with runtime packs with RuntimePackAlwaysCopyLocal = true, which is only the Microsoft.Windows.SDK.NET.Ref packs.

The _ResolveCopyLocalAssetsForPublish target adds _ResolvedCopyLocalPublishAssets items for assets from runtime packs for self-contained apps:

      <ItemGroup>
        <_ResolvedCopyLocalPublishAssets Include="@(RuntimePackAsset)" Condition="'$(SelfContained)' == 'true'" />
      </ItemGroup>

The _ComputeResolvedCopyLocalPublishAssets target (which depends on _ResolveCopyLocalAssetsForPublish) adds _ResolvedCopyLocalPublishAssets items from runtime packs where RuntimePackAlwaysCopyLocal is true:

      <!-- Include RuntimePackAsset where RuntimePackAlwaysCopyLocal is true -->
      <_ResolvedCopyLocalPublishAssets Include="@(RuntimePackAsset)"
                              Condition="'%(RuntimePackAsset.RuntimePackAlwaysCopyLocal)' == 'true'">
        <DestinationSubPath>%(ReferenceCopyLocalPaths.DestinationSubDirectory)%(ReferenceCopyLocalPaths.Filename)%(ReferenceCopyLocalPaths.Extension)</DestinationSubPath>
      </_ResolvedCopyLocalPublishAssets>

So for self-contained apps, the items from the Microsoft.Windows.SDK.NET.Ref pack get added twice. We should update the logic to avoid this.

This probably isn't related, but I just came across this issue when publishing with PublishTrimmed set to true

@dplaisted and @wli3, is this a known issue, or just related to windows?
