Custom Trace ID Generator in Open Telemetry .NET

[kiro1993]

Hi,

I'm looking for a way to customize generation of open telemetry trace id. This is part of how I'm initializing the tracer in the Startup.cs.

services.AddOpenTelemetryTracing(tracingBuilder =>
tracingBuilder
.AddSource(TracingConstants.ServiceName)
.AddAspNetCoreInstrumentation());

I tried using something like .SetIdGenerator(customIDGenerator); but couldn't do it.

these are the nuget versions im using:
"OpenTelemetry" Version="[1.2.0-rc3]"
"OpenTelemetry.Api" Version="[1.2.0-rc3]"

I tried using something like .SetIdGenerator(customIDGenerator); but couldn't do it.

Can you share the exact code you tried so we can check what was missing?

Would Activity.TraceIdGenerator help?
