title: Typescript debugging is not working on Visual Studio
body: <p>Trying to debug an angular 4 application + .Net Core 2.0 , but when putting the breakpoints on the typescript files I get the message Breakpoints will not be hit. No symbols have been loaded for this document."  However, I hit f5 to start the app and it doesn't start until I hit f12 to bring the google chrome tools window. It is a really weird behaviour. I notice that if i delete all the breakpoints from the typescript files and hit f5 it just runs normally.</p>
  
  <p>Any idea what could be the issue.</p>
  
  <p>Do not know if has something to do with the map files. Map files are just into the wwwroot folder for each ts file.</p>
  
  <p>Note: I am using visual studio 2017 Professional Edition</p>
