OpenTelemetrySourceGenerator

A source generator that creates extension methods to wrap interface calls with tracing (Activity/span).

What’s in the repository

  • sources/TraceUtils – attributes and runtime utilities.
  • sources/TraceUtils.SourceGenerator – Roslyn Source Generator.
  • sources/TraceUtils.SourceGenerator.Tests – generator tests (NUnit + Verify snapshots).

How to use

1. Project setup

Add the following NuGet references to the project:

  • TraceUtils
  • TraceUtils.SourceGenerator
  • OpenTelemetry (official .NET SDK)

2. Interface annotations

  • On methods: [ActivityOperation("OperationName", ActivityType.Internal)] — defines the operation name and activity type.
  • On arguments: [SpanTag("tag.name")] or [SpanTag("tag.name", shouldSerialize: true)] — writes parameters to the span as tags (the second option serializes complex types).

3. Calling generated methods

The generator creates extension methods in TraceUtils.Extensions:

  • sync: MethodNameWithTrace(...)
  • async: MethodNameWithTraceAsync(...)

Instead of calling _service.Method(...) directly, call _service.MethodWithTrace(...) so the invocation is captured in a span.

4. Registration in OpenTelemetry

When configuring OpenTelemetry TracerProvider, register the activity source from TraceUtils (via AddSource(TraceUtils.Utils.ServiceName)) so that generated spans are exported by the selected exporter.

using OpenTelemetry;
using OpenTelemetry.Trace;

// When configuring the trace provider:
builder.Services.AddOpenTelemetry()
    .WithTracing(tracing => tracing
        .AddSource(TraceUtils.Utils.ServiceName)
        .AddYourExporter(...));
