title: Unable to run analysis on SonarQube after upgrade to version 6.2
body: <p>I’m trying to run the analysis on SonarQube 6.2 using MSBuild scanner but I'm receiving an error immediately on the first C# file analyzed.<br>
  The error occurs also on a very simple test solution containing only two C# files.
  The error is the following:<br></p>
  
  <pre><code>SonarAnalyzer for C# version 1.20.1.1275
  0/2 files analyzed, starting to analyze: C:\TF\16\35\src\Net Projects\Solutions\Test\TestSonarQube\Program.cs

  </code></pre>
  
  <p>The analysis was working fine before the upgrade. The user used to run the analysis has full rights on all files to be analyzed. The files do not appear to be locked before the analysis.<br><br>
  I'm using the following configuration:</p>
  
  <ul>
  <li>SonarQube v. 6.2 </li>
  <li>C# Plugin v 5.5.1.522 </li>
  <li>Sonar scanner for MsBuild v2.2.0.24</li>
  </ul>
  
  <p>Here the full scanner log:<br></p>
