title: C# SDK Not Showing the Smartsheet-API namespace as an available reference
body: <p>I'm having a problem understanding how to use the API 1.1 in Visual Studio 2010 Professional.  Image 1 below proves the install of the SDK was successful.  This is the good news.  </p>
  
  <p>My problem is I can't reference the Smartsheet.API namespace.  When I try to do this via "using Smartsheet.API", I get a compile error.  I don't understand why I don't see "Smartsheet.API" in my project's list of references (see Image 2) below.</p>
  
  <p>Any ideas on what I'm doing wrong here?</p>
