dotnet-sos for .NET 9

tmds opened this issue · 7 comments

We have a test for debugging .NET apps using lldb and sos.
The test has been failing for our .NET 9 builds because there is no sos version that runs on .NET 9 yet.

When will there be a version of sos that runs on .NET 9?

The current released SOS should work just fine with .NET 9. What exactly is the problem?

tmds commented

The environment only has .NET 9 available.

The first command the test runs in lldb is dso, and that prints the following error:

Error: Failed to find a supported runtime within /path/to/dotnet_root/shared/Microsoft.NETCore.App/`

Sorry, you are right the released SOS tooling doesn't look for .NET 9 for hosting so if that is the only installed runtime you get that error message. The main branch does look for .NET 9. We need to do a tools release to get this fix. We will try to do that soon.

You can work around this by installing .NET 8 or below or building/using "main".
