Appinsights Instrumentation

This one hooks up Azure App Insights telemetry to ASP.NET Core or Node.js webapps running in Azure. It'll check what you're running and prefer auto-instrumentation for ASP.NET Core apps in App Service when possible, otherwise it walks through manual setup. That means either adding App Insights to your existing Bicep templates or using Azure CLI to spin up the resource, then modifying your application code with the right SDK calls. The context gathering is solid, it actually asks about your hosting setup before doing anything, which matters because the instrumentation approach changes depending on whether you're in App Service, Container Apps, or elsewhere. Good for when you need observability but don't want to dig through Microsoft's documentation maze.
