title: How to Downgrade to .NET Core 1.0?
body: <p>I am a beginner in .NET Core. I am learning Lynda's "Learn ASP.NET Core MVC The Basics" course. When I try to learn example code of Chapter 1, Video 5, this error appears:</p>
  
  <pre><code>HTTP Error 502.5 - Process Failure
  
  Common causes of this issue:
  The application process failed to start
  The application process started but then stopped
  The application process started but failed to listen on the configured port
  
  Troubleshooting steps:
  Check the system event log for error messages
  Enable logging the application process' stdout messages
  Attach a debugger to the application process and inspect

  </code></pre>
  
  <p>After going through several questions on Stack Overflow, I find that it is caused due to the inclusion of older .NET Core Version (1.0) in the exercise files. But the Visual Studio in my computer has Version 2.1.4. The folder "wwwroot" in the exercise might also cause the issue.  </p>
  
  <p>It seems that the only way I can fix this issue is by downgrading to Version 1.0. But how can I do it? Do I have to uninstall Visual Studio Code and install it with .NET Core V 1.0?</p>
