title: If I have .NET Framework 2.0 and .NET Framework 3.5, do I need .NET Framework 3?
body: <p>Say I have .NET Framework 2.0, 3.0, 3.5 installed for an Asp.NET web application.</p>
  
  <p>I realize that Framework 3.0 and 3.5 are just extensions to Framework 2, what is less clear is how 3.0 and 3.5 interrelate.</p>
  
  <p>Am I safe uninstalling Framework 3 if the Asp.NET application targets 3.5?</p>
