M1 Apple Monterey: Dotnet tool not found in zsh shell

[sshquack]

Describe the bug

Installing VS x64 on M1 Apple silicon macOS Monterey and launching a global tool does not work out of the box.

To Reproduce

• Install visualstudioformacinstaller-8.10.13.2.dmg (https://visualstudio.microsoft.com/vs/mac/) on a M1 with macOS 12.0.1
• Open a new Zsh shell and verify that the dotnet tools is in the $PATH

❯ tr ':' '\n' <<< "$PATH" | grep dotnet
/usr/local/share/dotnet
~/.dotnet/tools

• Install any dotnet global tool

dotnet tool install --global dotnet-format

• Try to run the globally installed tool

Exceptions (if any)

❯ dotnet-format
zsh: command not found: dotnet-format

Further technical details

• Include the output of dotnet --info

If ~/.dotnet/tools is in the $PATH, I would have expected the dotnet-format binary located at ~/.dotnet/tools/dotnet-format to have been found. Turns out this is because ~ is not expandable in $PATH?

To confirm this, if I explicitly add export PATH="$HOME/.dotnet/tools:$PATH" zsh was able to find the tool. So it seems like the dotnet installer for mac should add $HOME/.dotnet/tools to $PATH instead of ~/.dotnet/tools

[KalleOlaviNiemitalo]

Similar problems have been discussed in #22214 and #9415. The .NET SDK installer supposedly displays a message saying how to manually configure PATH for zsh; is that message at all visible when .NET SDK is installed by Visual Studio for Mac?

[sshquack]

@KalleOlaviNiemitalo There is a message when installing a tool using the CLI dotnet tool install ... but the VS for mac installer does NOT show this. I will add a comment to #22214 because it looks like a similar issue

The issue can be reproduced on Intel based macs. It's not an Apple Silicon (aka M1) issue.

@sshquack changing the content of the /etc/paths.d/dotnet-cli-tools file from ~/.dotnet/tools to $HOME/.dotnet/tools will not resolve the issue. The paths in the files in /etc/paths.d must be literal paths.
