Both ASP.NET Core and Microsoft.Extensions added new built-in metrics for Blazor WebAssembly and MemoryCache in .NET 11. It's high time to take a closer look at observability (or "o11y" to use a fancy numeronym) for local debugging and monitoring of production environments.

This live-coding session covers not only the three pillars of observability — logs, metrics, and (distributed) traces — but also its implementation in .NET in general and specific application models in particular. Moreover, we uncover the OpenTelemetry (OTel) standard, observe processes locally through CLI-based .NET tools and Aspire dashboards, and monitor deployed applications via Sentry.

The insights gained from this talk will help you to gain insights into all of your .NET apps to make error detection less painful and perhaps even aid in preventing problems in the first place.

This abstract was written manually, not by AI/LLM, regardless the usage of em dash 😉.
