Get notified if started process exited

I am Running a WPF application (process A). From this on a button click I need to start another process (process B), which is a WinForms application.

Now my question is if I close process B's window by clicking the (X)-button, which closes process B abruptly then how to notify this event info to process A?

The Process class has an Exited event for exactly this purpose. You also have to set EnableRaisingEvents to true to use it:

private void ButtonClick(object sender, RoutedEventArgs e)
{
    var process = new Process();
    process.StartInfo.FileName = "cmd.exe";
    process.EnableRaisingEvents = true;
    process.Exited += ProcessExited;
    process.Start();

    startButton.IsEnabled = false;
}

private void ProcessExited(object sender, EventArgs e)
{
    Dispatcher.BeginInvoke(new Action(() => startButton.IsEnabled = true));
}

if you are executing your external application using Process.Start then you can use WaitForExit method that will hold your cursor until the application is not exited. Take a look at this example to understand more about WaitForExit method on MSDN.
