```

<Alert level="info" title="Important Note">
When using OpenTelemetry to instrument HttpClient spans via `AddHttpClientInstrumentation`, you **must** set `DisableSentryHttpMessageHandler = true` in the Sentry options to disable Sentry's built-in HttpClient instrumentation. This prevents the creation of duplicate spans for HTTP requests.
