+- Unable to install because another NuGet packages depends on it error.
+
+ You will need to uninstall the NuGet package or packages that depend on "Microsoft.ApplicationInsights.Web" first. If you have multiple packages that depend on each other, you need to start with the package that nothing depends on first.
+
+    For example, if you have trace collection enabled you may receive an error like the one below when uninstalling Microsoft.ApplicationInsights.Web.
+
+   ![Error of being able to uninstall Microsoft.ApplicationInsights.Web because Microsoft.ApplicationInsights.TraceListener depends on it ](/media/remove-application-insights/uninstall-error1.png)
+
+    If that is case you will first uninstall the "Microsoft.ApplicationInsights.TraceListener" package, and then try uninstalling the  "Microsoft.ApplicationInsights.Web" again.
+
+    If you end up with another error that you can't uninstall "Microsoft.ApplicationInsights.TraceListener" because another package or packages depend on it you can look through those packages and find one that doesn't does not depend on anything to be uninstalled first.
+
+   ![Error of being able to uninstall Microsoft.ApplicationInsights.TraceListener because Microsoft.ApplicationInsights.Dependency Collector, Microsoft.ApplicationInsights.PerfCounterCollector, and Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel all depend on Microsoft.ApplicationInsights.WindowsServer depends on it](/media/remove-application-insights/uninstall-error2.png)
+
+    However in this case Microsoft.ApplicationInsights.Dependency Collector, Microsoft.ApplicationInsights.PerfCounterCollector, and Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel all depend on Microsoft.ApplicationInsights.WindowsServer but Microsoft.ApplicationInsights.WindowsServer depends on Microsoft.ApplicationInsights.Web.
+
+    Go back to uninstall Microsoft.ApplicationInsights.Web but this time in *Uninstall Options* select "Force uninstall even if there are dependencies on it" ("Remove dependencies" should still be selected). This will uninstall the package even if it's still being referenced in the project. This option could lead to broken reference in your project; if that happens you make need to [reinstall](https://docs.microsoft.com/nuget/consume-packages/reinstalling-and-updating-packages) those other packages. Then uninstall "Microsoft.ApplicationInsights.TraceListener".
+
+   ![Select force uninstall](/media/remove-application-insights/force-uninstall.png)
+
+- How to uninstall Microsoft.ApplicationInsights.TraceListener
+
+    If you would like to only uninstall Microsoft.ApplicationInsights.TraceListener, follow the steps in "Unable to uninstall because another NuGet package depends on it error" but instead force uninstalling Microsoft.ApplicationInsights.Web, force uninstall "Microsoft.ApplicationInsights.TraceListener".
