How to Performance Profile ASP.NET IIS web application with Visual Studio 2017?
Choose "ASP.NET" instead of "Running Process..." when choosing the analysis target.
I was running into some issues trying to run the Profiler (especially since windows home edition doesn't have the full IIS Set by default)
Since you are running Visual Studio 2017, It might be a lot easier to run the new diagnostics tool instead.
The Diagnostics tool is located under
Debug->Windows->Show Diagnostic Tools
It provides the Cpu Analysis and Memory Analysis just like the analyzer does.
You can set a breakpoint and analyze a small section of the code as well.
