#.NET Auto-instrumentation

The .NET auto-instrumentation provides automatic telemetry collection for .NET applications, including ASP.NET Core, Entity Framework, and other popular .NET libraries. This instrumentation captures traces, metrics, and logs without requiring changes to your application code.

The Operator injects the OpenTelemetry .NET automatic instrumentation into .NET application containers, configuring it to instrument common libraries and frameworks automatically. This enables comprehensive observability for .NET workloads running in Kubernetes.

#Enabling .NET Instrumentation

To enable auto-instrumentation for .NET applications, annotate your pod or namespace:

apiVersion: v1
kind: Pod
metadata:
  name: dotnet-app
  annotations:
    instrumentation.opentelemetry.io/inject-dotnet: "true"
spec:
  containers:
  - name: app
    image: myapp:latest

The Operator will automatically inject the instrumentation components and configure the .NET runtime to load them at startup.
