Problem installing with dotnet on M1 MacOS architecture

Hello

I have installed :
dotnet-sdk-3.1.417-osx-x64.pkg
on a MAC mini M1 arm64
and I have the following issue when I run dotnet :
/usr/local/share/dotnet/dotnet FootWorkService.dll
Failed to load A, error: dlopen(/usr/local/share/dotnet/host/fxr/6.0.3/libhostfxr.dylib, 0x0001): tried: '/usr/local/share/dotnet/host/fxr/6.0.3/libhostfxr.dylib' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), '/usr/local/lib/libhostfxr.dylib' (no such file), '/usr/lib/libhostfxr.dylib' (no such file)
The library libhostfxr.dylib was found, but loading it from /usr/local/share/dotnet/host/fxr/6.0.3/libhostfxr.dylib failed

There is no equivalent of dotnet-sdk-3.1.417-osx-x64.pkg for arm64 so what should I do ?

Best regards

    Only net 6 has an apple silicon support. You should be able to get 3.1 to run via rosetta. You can only build for intel macs, so any library you use must be intel. It appears a library you are referencing is arm.

    If you need arm support, then you will need to update to net 6.

    Hi @Olivier Paillat ,
    According to the documentation below, maybe you should try installing an older .net SDK.
    Visual Studio for Mac 8.10 and .NET on Apple Silicon machines
    Best Regards.
