 # Application Insights for ASP.NET Core applications
 
 This article describes how to enable Application Insights for an [ASP.NET Core](https://docs.microsoft.com/aspnet/core) application. When you complete the instructions in this article, Application Insights will collect requests, dependencies, exceptions, performance counters, heartbeats, and logs from your ASP.NET Core application.
 
-The example we'll use here is an [MVC application](https://docs.microsoft.com/aspnet/core/tutorials/first-mvc-app) that targets `netcoreapp2.2`. You can apply these instructions to all ASP.NET Core applications.
