title: WPF app not interacting with my Windows service
body: <p>I have a windows service which needs to open a WPF application based on an event.
  I am done with coding and when I run a WPF application instance through a process from my custom window service then it opens the app but hidden to me. </p>
  
  <p>I confirmed it's existence from task manager where my app instance has been created but APP GUI not visible to me.</p>
  
  <p>I also tried using "ProcessExtensions" class available on Github but that didn't help.</p>
  
  <p>Please suggest what should I do for this!</p>
  
  <p>Some saying for IPC mechanism but that I don't wanna use. Please let me know how can I achieve it!</p>
