I have .NET versions 1.1, 2.0, 3.0 and 3.5 installed. I want to know if I
really need all these versions or are they all backward compatible, meaning I
can uninstall all versions but the latest.

You only need them if you have apps installed that are developed to
leverage the framework. The versions are not necessarily backward
compatible, depending on how the app was written. Apps can be coded to
only work with a certain framework.

As 3.5 was only recently released I doubt you have any apps installed
that target that version, but you may in the future. My recommendation
would be that going forward, don't install every version of the
framework that comes out, only installing versions where you have
specific application requirements. As it is likely you don't know if
you have apps that requirement the framework, nor which version they
require, unless you have an urgent need to free disk space, there is no
need for you to remove any of the installed versions.

Which ones you need depends on what apps you run, and what the apps
need.

No. they are not.

No, you can not--not if you run applications that need earlier ones,
and many people do.
