title: Visual Studio Solution Unavailable (reload doesn't work)
body: <p>I am downloading a sample program for a barcode reader that I am using. Everytime I download the program and run it I am prompted with the error in my solution explorer (see image below).</p>
  
  <p>Any suggestions? Everytime I right click and reload project, it reloads quickly and then reverts back to unavailable.</p>
  
  <p>Suggestions? </p>
  
  <p>EDIT: Here is the link to the project (scroll to the bottom, PC Sample Program) </p>
