    The scenario in your first post won't work as you can't profile remotely. To profile the API you would need to install it on the server running the API.

    It also depends as to how you're connecting to the API on whether or not ANTS would be able to hook into the process.

    Thanks for you response. I have installed ANts profiler in the same server where api is running.

    These are .net core web api.
    so if i use the web api link for profiling no progress i cant see in the profiling.

    I'm facing the same issue.  I have a customized version of identity server set up on one site, running in .NET Core, accessed via one URL (, which we run in IIS and leverage the hosts file to set up the DNS name), and I have other sites on the same server that call into the identity server end-points.  I'd like to profile the identity server website.

    I have been able to profile the identity server website (at least the start up portion of the application, by launching as a .NET Core Application, specifying the assembly, indicating it is a web application, starting the web application in chrome, and specifying the launch URL of, but when I run the other websites (on the same server) that interact with the identity server (by making calls into, none of their calls are being profiled.  The calls are succeeding, but I suspect that they are bypassing the profiled identity server app, and are calling directly into the one configured in IIS.

    How do I get ANTS Performance Profiler to profile the version actually being hosted in IIS and that the other apps are calling?

    (Note that even on the profiled website, on the one started by ANTS, while it profiles the app startup, links and things I click on in the website that should be tracked aren't causing any profiling to occur...  After startup, there is no profiling activity).
