title: Changing target framework in Visual Studio 2008
body: <p>What's the deal with Visual Studio?</p>
  
  <p>I tried importing the Caching App Block and got this message:</p>
  
  <blockquote>
    <p>The assembly or one of its dependencies you're are trying to import requires a later version of .NET Framework.</p>
  </blockquote>
  
  <p>I went to the properties of my application in Visual Studio, but I can't find the dropdown to switch....what's the deal?</p>
