A four-part, hands-on series on instrumenting a .NET 10 system -- a Blazor Server frontend, a C# API over Postgres or SQL Server, and background jobs -- seeing all of it in self-hosted SigNoz, and preparing any .NET app for OpenTelemetry with only the BCL.

See what your Blazor Server app is really doing in production -- live circuits, stranded sessions, exhausted sockets, and your own business metrics -- with open-source, self-hosted tooling.

Follow one user click from the browser, through your ASP.NET Core API, down to the exact SQL query -- as a single trace in SigNoz, across Postgres and SQL Server.

Bring every cron script, legacy EXE, PowerShell task, and Python job into one dashboard you host yourself, no matter where each one sits -- from a job that only writes .txt files to one with a full OpenTelemetry SDK.

ActivitySource, Meter, and ILogger ship in the .NET runtime, not in OpenTelemetry. Instrument your app with them today at almost zero cost, read it back with built-in tooling, and bolt on a backend whenever you are ready.
