title: Is it safe to remove previous versions of the .NET framework?
body: <p>I've just installed the 3.5 .NET Framework and while doing some cleaning I've notice that I have a lot of older versions installed (1.1, 1.1 Hotfix(xxx), 2.0, 2.0 service pack etc...). I wonder if I can safely dispose of all of them or these are needed in case I run a lower version .net application.</p>
  
  <p>Thanks in advance.</p>
