| 8 | | File | Use when | |
| 9 | |---|---| |
| 10 | | [`references/setup.md`](references/setup.md) | Setting up the SDK via the DI/builder path (`AddOpenTelemetry().WithTracing/WithMetrics/WithLogging`, `UseOtlpExporter`, `OpenTelemetrySdk.Create`, `OpenTelemetry.Extensions.Hosting`), exporter wiring, env-var / `IConfiguration` inputs, and why there is no declarative YAML config in .NET. | |
| 11 | | [`references/api.md`](references/api.md) | Instrumenting with native BCL APIs (`ActivitySource`/`Activity`, `System.Diagnostics.Metrics.Meter`, `ILogger`), how the SDK subscribes (`AddSource`/`AddMeter`), attributes, propagation, and the optional OTel API shim. | |
| 12 | | [`references/instrumentation-libraries.md`](references/instrumentation-libraries.md) | Zero-code (the `opentelemetry-dotnet-instrumentation` CLR-profiler agent), the contrib instrumentation-package catalog, and manual instrumentation following semconv. | |
| 13 | | [`references/performance.md`](references/performance.md) | Tuning sampling, batch export processor, periodic metric reader, views, exporter choice, async context, graceful shutdown. | |
| 14 | | [`references/breaking-changes.md`](references/breaking-changes.md) | Auditing existing code for deprecated/renamed APIs and semconv changes across recent core/contrib releases. | |

| 18 | For YAML schema details (language-agnostic), see the `otel-declarative-config` skill — but note |
| 19 | .NET does not yet implement declarative config (see `references/setup.md`). |
