M1 macOS monterey: dotnet-ef fails with libhostfxr.dylib could not be found

File a bug

I moved from an Intel to an M1 Apple silicon recently. In the new machine dotnet-ef fails to run with error as shown below.

1. I installed Visual studio for mac x64 https://visualstudio.microsoft.com/vs/mac/ visualstudioformacinstaller-8.10.13.2.dmg

❯ dotnet --info
.NET SDK (reflecting any global.json):

  Microsoft.NETCore.App 5.0.11 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App]

2. I installed the 5.x of dotnet-ef tool

❯ dotnet tool install --global dotnet-ef --version 5.0.12
You can invoke the tool using the following command: dotnet-ef
Tool 'dotnet-ef' (version '5.0.12') was successfully installed.


❯ dotnet tool list --global
Package Id      Version      Commands
--------------------------------------
dotnet-ef       5.0.12       dotnet-ef

3. Here is the error when invoking

❯ dotnet ef
A fatal error occurred. The required library libhostfxr.dylib could not be found.
If this is a self-contained application, that library should exist in [/Users/ayemacair/.dotnet/tools/.store/dotnet-ef/5.0.12/dotnet-ef/5.0.12/tools/netcoreapp3.1/any/].
If this is a framework-dependent application, install the runtime in the global location [/usr/local/share/dotnet/x64] or use the DOTNET_ROOT environment variable to specify the runtime location or register the runtime location in [/etc/dotnet/install_location].

The .NET runtime can be found at:

4. I also tried completely uninstalling everything and starting from the scratch using sudo ./dotnet-uninstall-pkgs.sh (script here) but I keep running into the same issue.

How do I get dotnet-ef to work on M1?

Turns out this is not a efcore issue. The root cause is in the dotnet installer compat with Apple M1 arm64. Follow #27787 for details. Closing this.
