I'd probably separate package upgrades from just adding the platform. Also, adding new platform won't make LS load in Python Extension since it does its own platform checks and may or may not permit ARM. Extension needs to be modified to properly calculate URL for the ARM download.

My current solution：

Add linux-arm64 RuntimeIdentifiers and Build

dotnet publish -c release -r linux-arm64

Replace the output to the directory /home/ubuntu/.vscode-server/extensions/ms-python.python-2020.6.88468/languageServer.0.5.50/

Add permissions

sudo chmod +x Microsoft.Python.LanguageServer

Normal after reopen vscode

For what it's worth - and at the risk of introducing scope creep ...... linux-arm64 (in this case, native Linux on arm64/aarch64 on a Raspberry Pi...) ... But would this also work for Windows on ARM? And especially WSL2 on ARM?

Given that Microsoft has doubled-down on ARM (you gotta be pretty serious to make a custom processor and not something off-the-shelf), it seems wise to ensure that this runs not only on linux-arm64 but wsl2-arm64 win-arm64, etc.

Have you tried Pylance LS? It is in typescript so should run on any platform. https://devblogs.microsoft.com/python/announcing-pylance-fast-feature-rich-language-support-for-python-in-visual-studio-code/
