title: The type or namespace name 'ViewResult' could not be found (are you missing a using directive or an assembly reference?)
body: <p>I'm getting a lot of errors like the following:</p>
  
  <p>The type or namespace name 'ViewResult' could not be found (are you missing a using directive or an assembly reference?)</p>
  
  <p>The thing is when I double-click on one of the errors, it goes to the page, but the error goes away.  </p>
  
  <p>However, this happens when I try to run my project.  I can't build and run because these errors get thrown, but the errors disappear when I try to double-click on them.</p>
  
  <p>Is there a way to clear the cache for intellisense or somewhere else?</p>
