Can the 3.5 version of .NET Framework (currently Beta 2) be installed on
pre-Vista machines? Or is it Vista-only?
And, why doesn't .NET Framework come pre-installed with the operating
system? I think one of the main reasons people will reject such software is
having to install something first. I understand it might need upgrading, but
why do Windows machines come without any .NET Framework (or am I wrong about
this)?
It seems that .NET Framework should come with any Window OS, and that it
should auto-upgrade ala Windoes Update. It seems antiquated to require the
end-user to install something that is inert unless used, and is the basis of
all managed software written using VS!
Put simply, why isn't managed code supported by Windows NATIVELY?

It works on XP - haven't tried anything else.

Some newer Windows OS's do have a version of the .Net FW installed as
standard.

And the fact that the something is relatively big (20+MB).

The latter.

Unless I'm mistaken, I think it is a suggested installation via WU.

MS Research has a purely managed kernel (Singularity) under development, you
can read about it on their website http://research.microsoft.com/os/singularity/.
I like a lot of the ideas, you'll actually see performance improvements
based on static type checking instead of runtime checks. I'm not convinced
that the CLR equivalent layer is worthwhile, that may hurt performance, but
using static type analysis to enable high-performance message-passing IPC
should be a real hit.
OK. THen explain why my boss, who bought his computer this year, required me
to install .NET Framework 3.0 (re-distributable) on his machine before my
application would work, but worked fine once I installed it? If it is
pre-installed, why would I have to do this?

What version of Windows? Probably XP, and the discs were made before .NET
3.0 was released.
You might be right about my boss' computer.
Might be just bad luck, but in my experience I have never gotten a managed
program I've written using VS .NET (any version) to work unless I installed
the re-distributable on the target machine. Maybe I've always used the most
recent version of it for development, and my clients have always had older
computers. In truth, this is a likely scenario since I typically do use the
most up-to-date features and my clients in the past have typically not been
that computer friendly (or else why would they hire me? hehe).
What I'm working on now targets .NET Framework 3.0 so if I undersatnd
correctly, I'm probably good for all Vista machines natively and any
computer that can install the re-distributable (e.g., XP).

Ben:
This may be true in Vista, but I didn't think it is on XP. Are you sure?
AFAICT, only .NET versions 1.0 and 1.1 are present on my XP machines (I
have never installed VS2005 on these machines).

Actually I upgraded to 3.5 a while back. But VS VC++ 2008 Express has a
setting where I can set the level of .NET Framework I want to support. So
I'm hoping that means it will work on systems which have 3.0 or better.
This is supported if one looks at the References section. When adding
references if one changes the .NET Framework level it greys-out those no
longer available. Thus, if I set it to 3.5 none are greyed-out, but if I set
it to 2.0 many are greyed-out.

I suppose that depends on the definition of "auto-upgrade". It isn't
classified as a critical update, so it isn't forced on the user by Windows
Automatic Updates. However it should appear on the list of optional updates
in Windows Update, which is the best that can reasonably be done. At least
it did that at one point.
Normal users should be installing everything in the optional update list
anyway.
High criticality users should install only critical updates, and should not
be forced to install .NET Framework.
