title: VS2015 LINQ in debugger watch window
body: <p>According to my source <a href="http://blogs.msdn.com/b/visualstudioalm/archive/2014/11/12/support-for-debugging-lambda-expressions-with-visual-studio-2015.aspx">Debugging lamba expression with VS2015</a>, LINQ should work in the debugger's watch window. However, I still receive the following error:</p>
  
  <blockquote>
    <p>error CS1061: 'IEnumerable&lt;MyClass&gt;' does not contain a definition for 'Where' and no extension method 'Where' accepting a first argument of type 'IEnumerable&lt;MyClass&gt;' could be found (are you missing a using directive or an assembly reference?)</p>
  </blockquote>
  
  <p>Do I have to turn some option on? How to enable LINQ in the watch window? <code>System.Linq</code> is included via using in the file I'm currently debugging.</p>
