Answer 1

To extend @ChrisG's idea, a little, consider using process.MainWindowHandle and seeing if the window message loop is responding. Use p/invoke this Win32 api: SendMessageTimeout. From that link:

If the function succeeds, the return value is nonzero. SendMessageTimeout does not provide information about individual windows timing out if HWND_BROADCAST is used.

If the function fails or times out, the return value is 0. To get extended error information, call GetLastError. If GetLastError returns ERROR_TIMEOUT, then the function timed out.
