dotnet-ef requires x64 SDK on macOS Monterey with Apple Silicon (M1)

When installing the Arm64 version of the latest .NET 6.0 SDK (SDK 6.0.100-preview.7) on an Apple M1 Mac running the latest beta OS (macOS Monterey), the dotnet ef tooling fails to run properly and no error is given.

Steps to reproduce

1. Install the Arm64 version of the .NET 6.0 SDK dotnet-sdk-6.0.100-preview.7.21379.14-osx-arm64.pkg
2. Install the latest .NET 6 preview EF Core tools by running the command dotnet tool install --global dotnet-ef --version 6.0.0-preview.7.21378.4
3. Execute the command dotnet ef
4. The console (zsh) immediately returns and no error is provided

Additional Info

I tried several things to see if I could get an underlying message to display or log. The most telling was when I cd ~/.dotnet/tools/ and ran sudo ./dotnet-ef. This produced the following output:

zsh: killed     dotnet-ef

which when googled led me to the following closed issue https://github.com/dotnet/runtime/issues/48387

Current workarounds

1. Installing x64 version of SDK for global access to dotnet ef After trying several things, I decided to uninstall the Arm64 SDK and install the x64 SDK (dotnet-sdk-6.0.100-preview.7.21379.14-osx-x64.pkg) and was able to successfully run dotnet ef.

2. Installing dotnet ef locally As pointed out by @spahnke below https://github.com/dotnet/efcore/issues/25927#issuecomment-919802499, you can install dotnet-ef locally with the arm64 version of the SDK installed. Simply go to the root of you project/solution and execute the following two commands:

dotnet new tool-manifest
dotnet tool install dotnet-ef --version 6.0.0-rc.1.21452.10

Below is the result of a call to dotnet --info

I encountered the same issue and for me installing the tool locally in the project folder works even with the arm64 build of the SDK (both preview 7 and RC 1). It’s only the globally installed tool that fails.

Note: I’m currently only playing around with EF Core on my M1 Mac, so I can’t speak for every scenario. But I thought I mention it at least.

I think this is now tracked by https://github.com/dotnet/sdk/issues/21349 which is still open. That issue also shows yet another workaround by signing the global tool yourself.
