title: Is it possible to use C# 4.0 with Visual Studio 2008?
body: <p>I'm pretty aware that Visual Studio 2010 works with C# 4.0. But now I was wandering if I'm able to test C# 4.0 features with Visual Studio 2008.</p>
  
  <p>I did that one time, using C# 3.0 with Visual Studio 2005 hacking the app.config file.</p>
  
  <p>Did anyone have any success using C# 4.0 in VS2008?</p>
  
  <p>I've installed Net Framework 4.0 beta, rebooted, created a new WPF application, chosen Application properties, but the Target Framework can be set only to Net Framework 3.5.</p>
