title: .NETFramework,Version=v4.5 framework is a higher version than the currently targeted framework ".NETFramework,Version=v3.5"
body: <p>I created my first project in Framework 3.5 and i converted to framework 4.5 and its working perfectly. Secondly i tried to add the reference of this project to another project which is created in framework 4.5. while building my second project after adding the reference i am getting an error message:</p>
  
  <pre><code>1. The primary reference "xxx" could not be resolved because it was built against the ".NETFramework,Version=v4.5" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v3.5".
  2. The type or namespace name 'xxx' could not be found (are you missing a using directive or an assembly reference?)
  </code></pre>
  
  <p>pls advice where i am missing something</p>
