VSDbg vs2022 no longer works with arm32

[CoenraadS]

I am reporting this issue here, because this repository is mentioned in vsdbg.sh

When running vsdbg with vs2022 flag, it installs 18.0.10821.2.
This version crashes on arm32, with message FATAL ERROR: Failed to initialize dispatcher with error 8ede002b

Some googling reveals people mention to use version: 17.0.10712.2

However when trying to use vsdbg 17.0.10712.2 and Visual Studio 17.14.16, Visual Studio just gives Unspecified Error.

I also tried Visual Studio LTSC 17.10 (in support until January 13, 2026), same error.

Please provide information about the last working combination of Visual Studio 2022, and vsdbg that works with arm32.

I am not able to reproduce this problem. I tried Raspbian 13 (trixie).

What OS are you using?

That error message indicates that the .NET Runtime inside of vsdbg failed to start. The latest vsdbg is based on .NET 9. If you install the .NET 9 SDK on your OS, and try to run "Hello World", does it succeed?

[CoenraadS]

We do not have a .Net Runtime, this is an embedded firmware built using yocto.
Previously we were able to remotely debug our self-contained .Net 8 app using vsdbg and VS2022.

Our firmware is not Y2038 compatible (dotnet/core#9285)

Previously we could debug it using VS2022. Now we cannot. We don't want to use SDK 9 for anything until we have moved to a Y2038 compatible firmware.

We were previously able remote debug using vsdbg and vs2022. However some updates seems to have broken this.

How can we get a VS 2022 and VSDbg version that is built with SDK 8?

[gregg-miskelly]

Got it. In this case what you want to do is use version 17.14.10528.2. That is the last version that will use the .NET 8 runtime.

Thank you, I downloaded it from https://vsdebugger-cyg0dxb6czfafzaz.b01.azurefd.net/vsdbg-17-14-10528-2/vsdbg-linux-arm.tar.gz, and it seems to work.

@gregg-miskelly After installing manually installing 17.14.10528.2, Visual Studio can now list processes correctly, but when attaching we see this:

13:13:14.4500269 [Info, Thread 211]	liblinux.Shell.CommonCommandBase: Command "/bin/sh "/home/root/.vs-debugger/GetVsDbg.sh" -v vs2022 -u -l "/home/root/.vs-debugger/vs2022" -d vscode -a "/remote_debugger"" finished with exit code 255 after 271.7911ms

It tries to install vs2022 again?
