This tutorial will help you set up Service Profiler to collect and analyze performance data for your application.
You'll need to run Windows Server 2012 (Windows 8) and above on your target machines.
You'll also need .NET Framework 4.6.1 installed on your target machines, and this tutorial will also help you set this up.
Updating to .NET 4.6.1 is a ‘safe’ thing to do because it’s highly compatible with previous versions.
You DON'T need to upgrade your application targeting 4.6.1 or rebuild/republish your application.
