When I create new MVC app in .NET 6 Preview 2 in Visual Studio for Mac (Version 8.10 Preview (8.10 build 409)) I get this message as an output from debug. Unable to attach to CoreCLR. Unknown Error: 0x80131c3c.
Same problem I had with the stable build of Visual Studio for Mac (Version 8.9.1.34)

Configuration

  • macOS Big Sur 11.1
  • Apple M1
  • .NET 6 Preview 2 (6.0.100-preview.2.21155.3)
  • Visual Studio for Mac (Version 8.10 Preview (8.10 build 409))

We haven't shipped debugger support for Apple Silicon native with preview2. We are still working on deciding when to ship a beta

We shipped native preview debugger support with preview4+. VS Code debugger preview should be working.

I am not sure how VS for MAC will need to be changed. I suspect it won't work yet as it won't use the native debugger, but I am not sure yet.

VS Mac does not currently support using the native debugger. You should be able to use it with Rosetta if you have macOS 11.2 or later.

Closing this issue since .NET Core 6 preview 4+ supports Apple Silicon, and the .NET Core VS Code adapter has shipped with ARM64 support: https://github.com/OmniSharp/omnisharp-vscode/releases/tag/v1.23.12
