Visual Studio 2019 performance profiler error while collecting snapshots

Trying to get started with Visual Studio 2019 Performance Profiler to find memory leaks in an ASP.NET Core Web API application.

So, I choose the "memory usage" checkbox from the list.

Taking snapshots works fine too but when I click on "stop collection" button, I get a popup alert as "No Managed Heap data was collected. This feature requires .NET v4.5 or greater".

I tried installing .NET 4.5 but I do have 4.8 (as the installer reports).

Any clue on how I could get this thing working?

I am also interested to explore free/open source memory profiler alternatives.

I was using IIS express to debug/profile. For anyone facing this issue, use Kestrel(i.e. name of your application while choosing to debug profile).

Could it be document %windir%\system32\mscoree.dll and %windir%\SysWOW64\mscoree.dll. The file corresponding to the higher version could not be applied during the installation process, and it is still another lower version.
