Hello dipika,
I have had some annoyances with the big push to use application insights by MS. It does feel a bit heavy handed as often it is on by default. I could be wrong but most of the templates I have experienced do have a option for application insights
that is on by default.

Another thing you can try is removing telemetry from the httpModules secton in system.web and system.webservice. You should also remove the references to telemetry. I suggest using the NuGet Package Manger to do this in the first instance. In
my experience it does a good job of cleaning things up but you might find the web.config will need a review afterwards.
Good luck!
Jeff
