title: VS 2010, Solution Explorer not showing
body: <p>OK recently I uninstall NuGet Packages because I had to install MVC 3 and I already had MVC 4 installed and for some reason it gave me an error with the NuGet version when trying to install MVC 3. So after uninstalling NuGet I proceed to install MVC 3 and it went Ok. But for some reason my <strong>Solution Explorer View stop working</strong>. </p>
  
  <p>If I open a new Visual Studio instances and open any project the solution explorer is not visible, if I try to open it via View -> Solution Explorer nothing happens. When I run the project the Solution Explorer view appears but with an error. This error:</p>

  <p>I don't know how to run with the /log parameter. </p>
  
  <p><em>What's going on with my solution explorer view?</em></p>
  
  <p><strong>Edit 1</strong>: Has <code>@Rocky</code> suggested I run with <code>/log</code> and the <code>ActivityLog.xml</code> have the following structure:</p>
  
  <pre><code>&lt;entry&gt;
      &lt;record&gt;304&lt;/record&gt;
      &lt;time&gt;2014/10/14 19:19:29.988&lt;/time&gt;
      &lt;type&gt;Information&lt;/type&gt;
      &lt;source&gt;VisualStudio&lt;/source&gt;
      &lt;description&gt;PERF: Shell start. 43011 ms&lt;/description&gt;
  &lt;/entry&gt;
