Process ID returned by FlaUI.Core.Application is different from windows process ID

[amit83pandey]

Describe the bug
The process ID returned does not match the original process id of the target application. How can I get the exact process ID of any application that I launch from the library?

Code snippets
public FlaUI.Core.Application application = FlaUI.Core.Application.Launch(appPath);
application = FlaUI.Core.Application.Attach(application.ProcessId);

Screenshots

Additional context
Same code works fine on some of the variants of Windows.

You are probably running into the issue that the calculator is a windows store app which you need to start differently. Try it with an application that is not a Windows Store App (like notpad++) and there it should work.

We were having issues also launching the calculator on W11 and this old response of @Roemer was the key.

In our case:

var app = FlaUI.Core.Application.LaunchStoreApp("Microsoft.WindowsCalculator_8wekyb3d8bbwe!App");
and getting the parent to interact with it
var window = app.GetMainWindow(automation).Parent.AsWindow();
