  18. Browse the listening URL
  19. Press Ctrl+C to stop
  20. To Debug, Open the HomeController.cs and set the breakpoint in Actions
  21. From the Menu, RunàStart Debugging
  22. Browse the listening URL your breakpoint should hit at this time
  23. To Stop, Run–>Stop Debugging
  24. To run in a container, you first need to build the container with DockerFile
  25. Press Ctrl+Shift+P, type docker file to add the docker file then select “Add Docker Files to Workspace” From the next screen select “.NET ASP.NET Core” From the next screen select “Linux”.
