title: How to get source code of .NET libraries to VS
body: <p>I was told that Microsoft has released reference source code for some .NET libraries (I'm especially interested in C# libraries). If it is true, I would like to download that code and use it with my VS, so I can browse the code by selecting </p>
  
  <blockquote>
    <p>Go to Declaration</p>
  </blockquote>
  
  <p>and </p>
  
  <blockquote>
    <p>Go to Implementation</p>
  </blockquote>
  
  <p>from context menu. It would be much better then just to see documentation in object browser.
  So how do I get VS to work with it? Thank you.</p>
