Could not load file or assembly 'Tools, Version=4.5.0.0, Culture=neutral, PublicKeyToken=f7660c0f5438cda5' or one of its dependencies
<p>Initially opened a project in Visual Studio 2012 and now when opening it in Visual Studio 2010 I am getting this error:</p>

<blockquote>
  <p>Reference.svcmap: Could not load file or assembly 'Tools,
  Version=4.5.0.0, Culture=neutral, PublicKeyToken=f7660c0f5438cda5' or
  one of its dependencies. The system cannot find the file specified.</p>

<p>Again opening it in 2012 also prompting for the same error and i have my project on version 3.5. I have no clue why it is asking for 4.5?</p>
