We currently don't support sos and dump on riscv. As for global tools, this would be the SDK work more than diagnostics.

[hoyosjs]

@akoeplinger @steveisok do y'all know what the mono SDK support here is and who'd look at refemit in that case?

As far as I know, we don't have a riscv runtime with mono.

[akoeplinger]

Yeah this is running on coreclr.

[hoyosjs]

Oh, sorry. Forget riscv is coreclr based. Thanks folks. That being said, this is an SDK tool issue. Let me ask what the state of SDK is currently.

You might be able to workaround by changing this here to always return SerializationMode.ReflectionOnly so XmlSerializer skips generating the temp assembly: https://github.com/dotnet/runtime/blob/0a5e97f46fb4ddf4f0ec41889243ed99e704fa95/src/libraries/System.Private.Xml/src/System/Xml/Serialization/XmlSerializer.cs#L118
