Both the C# extension and C# devkit appear to be crashing with various errors. Possibly due to running a linux x64 container on an arm64 machine.

There's no consistent place that the crash happens, I've seen any of the following errors:

[stderr] Unhandled exception: [stderr] Microsoft.VisualStudio.Composition.CompositionFailedException: An exception was thrown while initializing part "Microsoft.VisualStudio.Composition.PassthroughMetadataViewProvider".

@jubalaaronmurrian a workaround that seems to work on my end is to add the line

ENV DOTNET_EnableWriteXorExecute=0

in my dockerfile.

I don't think there is anything we can do on the extension side to resolve this. As far as I understand it, it looks the runtime isn't able to detect that its running under rosetta emulation inside the container, and so cannot disable an unsupported feature.

See dotnet/runtime#94909
dotnet/runtime#80733
dotnet/runtime#97828

Closing as external.

@dibarbet
Thank You, the workaround worked for me also.
