title: Changes in HTML not reflected in browser
body: <p>EDIT:
  From what I am seeing, this is extending past a single project and must involve how I am handling building/running a project:</p>
  
  <p>NEW BEHAVIOR,
  I download the original project that I am basing my project off, in .Zip form
  I extract the file and open the solution.
  I click run and the project begins to build.
  A browser opens up and displays my previous project. (a completely different solution)</p>
  
  <p><em>So I am creating a web application using Angular 6, net core 2.1, ef core 2.1...
  I had built the front end, however--now the behavior that I am experiencing is that when I change any of my HTML code, the changes are not reflected inside of the browser.<br>
  Some things I have tried:
   1. Comment everything out.  Effect:  Nothing changes in browser.
   2. Change the filename of the HTML.  Effect: breaks the web application.
   3. Change filename back to normal, delete all html code.  Effect:  Application working again, still showing old content.<br>
   4. Clean browser cache.  Effect: None
   5. Force refresh (Control f5).  Effect: None.
  Does this sound familiar to anyone?</em></p>
