☹️ Sorry friends, I’m still trying to get access to an M1 so I can dig into this.

My mistake, it is not completely fixed, dotnet --version, build, run is working, but the ef scaffold is not

The SDK team says this is a known issue. The x64 and arm64 installers stomp over each other and cause problems. Try uninstalling, deleting everything under /usr/local/share/dotnet then try again.

solved!

Correct me if I’m wrong, but I think the only remaining issue here is just a duplicate of #25927.

@johnseed Can you try with Npgsql.EntityFrameworkCore.PostgreSQL now that preview 6 is released?

ajcvickers on Aug 6, 2021

I guess it is fixed in preview6, but the debugger not working with Visual Studio for MAC, that’s another issue.

Unable to attach to CoreCLR. Unknown Error: 0x80131c3c

johnseed on Jul 15, 2021

Update: doing some cleanup (removing old versions) and reinstalling did make it work

dotnet --version
6.0.100-preview.6.21355.2

Don’t really get what happened there.
