How to Trace Anthropic SDK Calls With the Built-In OpenTelemetry Export

The Anthropic Python and TypeScript SDKs now emit OpenTelemetry spans on their own: register a tracer provider before the first call and every messages.create becomes an anthropic.messages.create CLIENT span with gen_ai.* token, model and stop-reason attributes. Content mode, conversation IDs, user.id baggage, linking to the Claude Platform's server-side spans, streaming and tool runner behavior, and the env-var override trap, checked against anthropic 2.8.0.

OpenTelemetry .NET 1.20: ConfigureSampler lets libraries wrap the app's sampler

OpenTelemetry .NET 1.20.0, released on October 15, 2026, adds TracerProviderBuilder.ConfigureSampler. A library can now wrap the sampler the SDK resolved from SetSampler, OTEL_TRACES_SAMPLER, or the default, instead of silently overwriting it.

How to add the current user id to every log entry in ASP.NET Core

A BeginScope middleware misses the exception handler's error log and the Request finished line. Register an ILogEnricher that reads the user from IHttpContextAccessor, open a scope only when work leaves the request, and watch out for Serilog's AddSerilog silently cancelling enrichment.

How to add Aspire to an existing ASP.NET Core solution without restructuring it

Add Aspire 13.4 to a brownfield ASP.NET Core solution by adding two new projects and three lines per service: aspire init, AppHost wiring with AddProject and WithReference, keeping your existing launchSettings.json and connection strings, and the resilience, health-endpoint, and proxy gotchas that bite on day one.
