.NET Source Generator for interface-based telemetry. Supporting activities, logs, and metrics.

The purpose of this application is to show how to integrate logs (via Serilog), health checks (via Microsoft AspNetCore HealthChecks), business metrics (via Prometheus) and traces (via Elastic APM) to an Elasticsearch cluster with .Net.

A file-based storage for OpenTelemetry traces (activities) that is suitable for isolated embedded and desktop applications.

Release observable features by using FeatureGates, instrumented abstractions that replace 'if' statements.

This project demonstrates how to implement observability in .NET applications using OpenTelemetry.
