Do I need all Microsoft .NET Framework versions?

Is this safe to uninstall older NET. Frameworks? I'm currently using the v4. Can I uninstall the 3 previous one that eat space on my laptop, or, this action will break the latest version (which, in fact, relies on some pieces in the previous ones, for instance) ?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Do they really take up that much space? – BoltClock Sep 29 '11 at 9:01
Not that much, but I have no more space left, so it's an option to consider if it's not armful. In fact I have the same question about Visual Studio 2008 and 2005... Can I unistal them ? :-) – Pierre Sep 29 '11 at 9:04
+1 for asking this, i also want to know – Bravo Sep 29 '11 at 9:05
Are you really asking if you can uninstall Visual Studio 2008 and 2005 from your own machine? The answer is you can do anything you want. – Ramhound Sep 29 '11 at 11:24
"exact duplicate"... You must be joking. – Pierre Sep 29 '11 at 13:37

In general, yes, however note that if you are doing development work in IIS and have application pools configured to use previous versions then strange behaviour may happen.

The overhead is not great, however, so unless you're really short of space I'd not bother.

The safest way is to uninstall all of them (in the opposite order - 4, 3.5, 3, 2, 1.1, 1.0) and then install v4.
