Target machine is an embedded ARM Cortex-A7 - but it will fail on any non-x64 architecture.

Steps to reproduce

Follow the remote debugging guide: https://github.com/OmniSharp/omnisharp-vscode/wiki/Attaching-to-remote-processes

The critical step is the VSDBG installation on the server.

curl -sSL https://aka.ms/getvsdbgsh | bash /dev/stdin -v latest -l ~/vsdbg

Expected behavior

An ARM debugger is installed.

Actual behavior

The script fails to determine the RID. It seems only x64 RIDs are supported, I tried to supply several RIDs manually, but the download only works for very few x64 RIDs. My application is successfully targeting -r linux-arm. See https://github.com/dotnet/corefx/blob/master/pkg/Microsoft.NETCore.Platforms/runtime.json for a list of RIDs.

I see that this is the same debugger that Visual Studio 2017 uses and not part of the OmniSharp project. Who is responsible for those mysterious debuggers and why are they built for x64 only? Is it part of an open source project (hope) or closed source (hopeless). Any directions are welcome. Remote debugging is essential for ARM devices!

We haven’t yet tried any distro aside from Raspbian, but we have our first beta release up. Instructions for anyone who wants to try it: https://github.com/OmniSharp/omnisharp-vscode/wiki/Remote-Debugging-On-Linux-Arm

We have updated the aka.ms URL that VS uses to download vsdbg, which includes the fix to detect arm platform. Debugging linux-arm from VS should just work^TM now.
