I opened Visual Studiio.  Created a WPF project,  Just to ensure everything was worked I add nothing to the form.  When I click Start Debugging the App acts like it is starting.  Then their is a flash on the screen and nothing happens. I go back to Visual Studio and I have to Stop tge Debugging process.
I must have done something wrong.  What gives.  PS  No error messages.
 So much for attempting to learn something new.
