Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5

[bbentley52]

So now after this massive update, 248M, I now have 4 versions of the .Net
Framework installed on my PC. I spent 37+ years on a large IBM Mainframe, and
generally speaking you never had more than 2 versions installed. One for
Production and one for testing.

Is it really necessary to have all 4 Version installed? ( 1.1 2.0 3.0 and
3.5 )

I also have a Dell Netbook with a small HD and having unnecessary software
is a very important issue.

What is the recommendation from an Expert on this topic?

Thanks for your assistance.

This has nothing to do with production vs. testing.

The .net framework files are run-time files needed by programs written
using .net. Programs written with .net need the corresponding version
of the .net framework, so you very likely need them all.

You wouldn't have, e.g., .NET Framework 3.5 installed if there wasn't an
application installed that depended on it. (If it's not already installed,
the .NET Framework version is typically installed when you install the
application.)

And if you have .NET Framework 3.5 installed, it only makes sense to install
a Service Pack which "contains many new features building incrementally upon
..NET Framework 2.0, 3.0, 3.5, and includes cumulative servicing updates to
the .NET Framework 2.0 and .NET Framework 3.0 subcomponents." [Source:
Download Center page for .NET Framework 3.5 SP1]

Thanks for the info. I did not install 3.5 - It came from Automatic Updates.
I did not install 3.0 - It also came with the Automatic Update.

Is there a Tool, that would tell me if ANY software I have installed,
requires .Net Framework at all ??

All the versions I have installed, came from Microsoft Automatic Updates.

Thanks Ken. I know that your answer is not entirely correct. According to
MSFT, an application written with 1.1, will run under 2.0, if 1.1 is not
installed.

 

[SC Tom]

I think (and I may be wrong) what bbentley is trying to find out is, are all
of the different versions necessary? For example, on my home PC, I have 1.1,
1.1 Hotfix, 2.0SP1, and 3.0SP1. Do I need all of these? Can't I just
uninstall everything other than 3.0SP1, or is it not backwards compatible to
the earlier versions? I think it's a valid question, and unfortunately, I've
never dealt with .NET enough to know the answer.

Right On SC Tom. That is what I would like to know. Why waste HD space with
unneeded software.
Java is famous for installing the next version without cleaning up the old
version.
( I do that by hand.)

Yes, I know that I oversimplified slightly. But the important word is
"slightly."

P.S. - Nice to see another "Retired" IT Professional. I just wish MSFT would
view their forums from time to time. It would be nice to get an answer from
the source, rather than trying to decide which responder knows your problem.

From what I understand, these versions (1.1, 2.0, 3.0, 3.5) are not just
later versions of the original, they are stand alone programs. It is
unfortunate that they used a numbering system that implies newer versions of
the same program.

Believe it or not, yes. Sadly, as versions progress, they don't retain
support for older versions. By that I mean if an app specifically
calls for .NET 2.0 and you have 3.5 installed, 3.5 won't give the app
that wants what .NET 2.0 has what it needs. I think it's dumb that
there is no backwards compatibility built into the newer .NET
versions. I can see that in a few years, people will have 5-10 version
of .NET installed. It is a bit ludicrous and I hope the folks at
Redmond realize this pending catastrophe and address it somehow.

I don't see why you wouldn't be able to remove .NET 1.1 since most
modern apps and updates to them are calling for a minimum of .NET 2.0.
If it breaks something, you can always re-install the version you
remove.

Well.........THe folks at Redmond didnt seem to know that the end of the

Century was coming in 1999. So I wouldn't hold my breath until they realise
we all have 100+ versions of .net on our PCs

Heh, what can ya do.
