Application Insights Profiler is installed with the Windows Azure Diagnostics extension for VMs. The extension needs to be configured to run the profiler and the App Insights SDK must be built into your application.
 
 1. Add application Insights SDK to your [ASP.Net application](https://docs.microsoft.com/azure/application-insights/app-insights-asp-net) or regular [.NET Application.](https://docs.microsoft.com/azure/application-insights/app-insights-windows-services?toc=/azure/azure-monitor/toc.json) You must be sending request telemetry to Application Insights see profiles for your requests.
