Resources

`dotnet-trace`

is a standalone CLI program
works only with .NET Core 3.0 Preview 5 or later
either attaches to a running process or starts a process itself, depending on arguments
always captures .nettrace format, if speedscope is specified, it’s just converted at the end of the run
may be possible to bundle as a precompiled lib with Native AOT?
actually profiling NativeAOT compiled code wouldn’t be possible at least until .NET 8: https://github.com/dotnet/runtime/issues/79241

Two PRs need to get in in order to accept your profile:

Add donet as a platform: https://github.com/getsentry/relay/pull/1885
Deprecation of some fields: https://github.com/getsentry/relay/pull/1878

Looking at your profile, a few things I saw you’d need to correct:

timestamp needs to be RFC3339 formatted, like 2023-03-01T10:10:10.123456789+06:00 (the more precision the better, down to the nanosecond if possible).
os.build should be os.build_number and os.build_number should be os.version
transaction.id needs to be a uuid4 without -
there’s no field id in thread_metadata values
