Your host architecture is x64 rather than ARM64 - are you sure you installed the correct installer?:

Installing .NET and runtime on macos M1 does not work

I had the wrong version of .NET installed and removed the .NET SDKs and .NET runtimes.
When I run dotnet --info to confirm, I get this output:
Host:
Version: 7.0.0
Architecture: x64
Commit: d099f075e4
.NET SDKs installed:
No SDKs were found.
.NET runtimes installed:
No runtimes were found.
Other architectures found:
arm64 [/usr/local/share/dotnet]
registered at [/etc/dotnet/install_location_arm64]
Environment variables:
Not set
global.json file:
Not found

When I download .NET 7.0 SDK (v7.0.402) - macOS Arm64 Installer and run install, the installation goes through without a problem but when I then (even after restart) runs dotnet --info again, or other commands, I cannot verify the installation.
Following the installation guide, does not seem to do the trick for me.
When I ran the wrong version for MacOS M1, I was able to run, and build C# programs, but not run the debugger.
The device is a MacBook Air (M1, 2020) - OS BigSur 11.6, and I run Visual studio code Version: 1.83.0 (Universal).
What should I do?

2023-10-12T19:25:28.0966667+00:00 Thanks Paul, but this version is not compatible with an M1 chip, right?

which dotnetShould verify you are using x64 path
/usr/local/share/dotnet/dotnet --versionshould be the arm version. you probably just need to update your path.

2023-10-12T19:31:23.2833333+00:00 Thank you Bruce!
Out of curiosity, how do you find out that it's via Rosetta?
Running
which dotnetreturns
/Users/wiro/.vscode-dotnet-sdk/.dotnet/dotnetand
--versionreturnsThe command could not be loaded, possibly because: * You intended to execute a .NET application: The application '--version' does not exist. * You intended to execute a .NET SDK command: No .NET SDKs were found. Download a .NET SDK: https://aka.ms/dotnet/download Learn about SDK resolution: https://aka.ms/dotnet/sdk-not-foundSo I assume this is because I do not have .NET SDKs installed (as it says..).
I am still puzzled if there is a way to change the architecture (if this is what I should do) so that I work with ARM instead, given that I run an M1 chip.

2023-10-12T21:56:28.4233333+00:00 You should check the architectures of the installed dotnet:
% file /usr/local/share/dotnet/dotnet /usr/local/share/dotnet/dotnet: Mach-O 64-bit executable arm64 % file /usr/local/share/dotnet/x64/dotnet /usr/local/share/dotnet/x64/dotnet: Mach-O 64-bit executable x86_64if the first one is not arm, then your base install was x64 (intel). you need to uninstall and reinstall.
I have no idea what:
~/.vscode-dotnet-sdk/.dotnet/dotnetis and why its in the path before the real dotnet app:
/usr/local/share/dotnet/dotnetcheck your path:
% env | grep PATH
