title: Opening project in Visual Studio fails due to nuget.targets not found error
body: <p>So I downloaded Twitterizer from <a href="http://www.twitterizer.net/downloads/" rel="noreferrer">http://www.twitterizer.net/downloads/</a></p>
  
  <p>I try to open it in Visual Studio and get all these nuget errors:</p>
  
  <pre><code>The imported project "C:\Twitterizer\.nuget\nuget.targets" was not found. 
  Confirm that the path in the &lt;Import&gt; declaration is correct, and that the file 
  exists on disk.
  </code></pre>
  
  <p>What is going on. How do I deal with this?</p>
