title: Enable XSD as Type Definition Language is Disabled
body: <p>I came from this question : <a href="https://stackoverflow.com/questions/14385679/how-to-install-contract-first-tool-in-visualstudio-2012">How to install Contract-First Tool in VisualStudio 2012</a> </p>
  
  <p>When I tried to perform the steps mentioned by the answer of that question, which is also what is mentioned in the topic <a href="http://msdn.microsoft.com/en-us/library/hh674270.aspx" rel="nofollow noreferrer">Contract-First Tool</a>, I faced the following problem: The options <strong>Enable XSD as type definition language</strong> and <strong>Validate WCF configuration when building the project</strong> are <em>disabled</em>.</p>
  
  <p>The XML Schema generated is valid and it was taken from the aforementioned tutorial.</p>
  
  <p>Why is that happening?</p>
