title: How to set the "Target Framework" in visual studio 2013?
body: <p>I am new to C# programming and don't know how to set the "Target Framework" in visual studio 2013? When I right click on the project -> Properties I see no left column of the property pages window with no Application tab.
  I tried to build a solution and I got several errors like this:</p>
  
  <blockquote>
    <p>Error 6 The type or namespace name 'ObjectSet' could not be found (are you missing a using directive or an assembly reference?)</p>
  </blockquote>
  
  <p>And then I found this answer
  <a href="https://stackoverflow.com/questions/5567945/type-or-namespace-name-does-not-exist">link</a></p>
  
  <p>But I don't actually know how to change the target framework. Please help me. Thank you in advance. </p>
