title: Development Server hot updates not working
body: <p>I upgraded my .NET Core 2.1 project to Angular 6 and everything seems to be working correctly except for hot-updates. Before updating it was possible to update the TypeScript and VS would re-compile and reload the browser, now that seems to be broken along with having to manually run <code>ng build</code> to recompile the scripts, VS doesn't seem to recompile automatically anymore.</p>
  
  <p>Is there a setting, possibly in angular.json that I need to set to enable the development server?</p>
  
  <h2>Update</h2>
  
  <p>For some reason, Hot Updates started working temporarily and not sure what I did to get it to start/stop working. When I start a debug session and update any of the .ts files, I can see the compiler output succeeding but when I refresh my browser I don't see any of the changes unless I manually build the project using the <code>ng build</code>.</p>
  
  <p>I am starting to think that there is some miscommunication going on somewhere or possibly an error somewhere that isn't being picked up by the compiler causing something not to update?</p>
  
  <p>Another thing I noticed while watching my output window is my site starts running on localhost:44359 but in the output, it says <code>Angular Live Development Server is listening on localhost:55287</code> should these ports match?</p>
  
  <p>one last observation I have made is after a change has been made during a debug session the output window lists all the chunks just like when running it manually with the exception it outputs <code>i ∩╜ówdm∩╜ú: Compiled successfully</code> could something be corrupt or is this simply an output bug?</p>
