Vista - Microsoft .NET Framework xx - which one?

I see today that 3 versions of MS .NET Framework have been updated
- version 3.5
- version 3.0 SP1
- version 2.0 SP1

Do I need any of these with Vista? What for? Any why are there almost as
many falvours as Vista, co-existing at the same time?

Thanks for any clear explanations

There is a good video on Microsoft's Channel 9 that may help explain why
multiple versions exist.

.Net is a programming system that Microsoft came up
with in 2001. It's sort of Microsoft's version of Java. Like
Java, software written in .Net needs a large collection of
support files, which Microsoft calls a "framework". (In Java
it's called a "virtual machine".) Without those files, the
software can't run.

Since 2001 there have been several versions of the
..Net system and therefore the .Net framework. They
are not all entirely compatible. So if you have any .Net
software installed you may need one or more of the
frameworks. You may not have any .Net software. It's
not very commonly used for standard "desktop" software.
It's used more for things like "web-based" software on
corporate intranets, again like Java. But there are a few
programs written in .Net for the desktop.

So, do you need the framworks? Maybe. Maybe not.
If you don't mind 100MB+ of possibly superfluous extra
stuff on your system then you can have all the frameworks
and not worry about it. If you want to have a lean system
for some reason, you can try uninstalling all frameworks
and then see if all of your software still works OK. The
sign that you are trying to run .Net software without the
required framework is that you see a message saying
something like, "mscoree.dll was not found".

Obviously I do not need 2.0, 3.0 or 3.5 - else I would have seen an
error or two.

Which ones target which - is what i would like to know? I appear to have
1.1, but am not sure if I need to keep it.

The only option open to me appears to be to uninstall it, and see if I
get error prompts.

The application would specify that during setup and all you would have to do
is download and install it.
