Error building net7-macos target with PublishSingleFile #16754

Open cyanfish opened 2 years ago

cyanfish commented 2 years ago

Steps to Reproduce

  1. Create an empty project and set it to a macos target (e.g. net7.0-macos10.15) with a basic plist file
  2. run dotnet build ProjectName -r osx-arm64 -p:PublishSingleFile=true -p:UseAppHost=true

I've been able to reproduce with both net6 and net7 running on an M2 Macbook. Building for arm64/x64 doesn't make a difference. Using publish instead of build doesn't make a difference. Without PublishSingleFile it generates an .app bundle as expected.

Expected Behavior

The build should succeed and generate an .app bundle with a single-file binary. (My goal is to generate both x64 and arm64 single-file binaries so I can lipo them into a universal binary.)

Actual Behavior

/usr/local/share/dotnet/sdk/7.0.100/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Publish.targets(904,5): error MSB4018: The "GenerateBundle" task failed unexpectedly. [/Users/ben/Devel/SingleFileBug/SingleFileBug/SingleFileBug.csproj]

We don't support PublishSingleFile at the moment, so this is expected.

I'm keeping this open so that we can show a better error message.
