title: Visual Studio 2015 or 2017 shows IntelliSense errors but solution compiles
body: <p>We are currently evaluating the new Visual Studio 2015 and encountered a strange problem with IntelliSense. When I compiled our main solution with the new studio the build succeeds, but nevertheless 6 errors are shown. </p>
  
  <p>I discovered that it's not a real error, but only an intellisense error. The code is definitely correct and everything compiled successfully. The code however is marked red and errors show up in the error list.</p>
  
  <p>All 6 errors have the same origin. It's a simple constructor call. Strange enough, but there are also some occurrences of the exact same constructor without any errors.</p>
  
  <p>The error message:</p>
  
  <pre><code>Code: CS1729
  Message: '&lt;the class&gt;' does not contain a constructor that takes that many arguments.
  Project: &lt;the project name&gt;
  File: &lt;the path to the file&gt;
  </code></pre>
  
  <p>The new studio was installed on a freshly installed Windows 7 without any legacy software (no VS13).</p>
  
  <p>I've already tried to clear the caches, deleted the suo file, deleted bin and obj directories, cleaned and rebuilt the solution etc. But nothing worked.</p>
  
  <p>Can anyone explain that behavior to me?</p>
