Api Windows c # window handler

For Windows automation, be it UWP (Universal Windows Platform Application) or the legendary Winforms Win32 (called Classic Windows Application) you can try WinAppDriver - Windows Application Driver

What is basically WinAppDriver? You can automate UI in the same way that is done for example in Selenium Driver . That is, by C # code in this case of your need, to be able to manipulate the UI of the target application.

See the example for notepad

// Launch Notepad
DesiredCapabilities appCapabilities = new DesiredCapabilities();
appCapabilities.SetCapability("app", @"C:\Windows\System32\notepad.exe");
appCapabilities.SetCapability("appArguments", @"MyTestFile.txt");
appCapabilities.SetCapability("appWorkingDir", @"C:\MyTestFolder\");
NotepadSession = new WindowsDriver<WindowsElement>(new Uri("http://127.0.0.1:4723"), appCapabilities);

// Use the session to control the app
NotepadSession.FindElementByClassName("Edit").SendKeys("This is some text");

There are several examples in the repo
