my control panel -> add/remove programs shows that there are 2 .net
framework versions installed: 1.1 and 1.0.3705

It shows that the 1.0 version is used most recently. The other's last use
was a year ago. In my MS Visual C# about, it shows that 1.0 is the one
being used.

Now I'm told that there are 2 new ones to be updated: Framework 1.0 SP3 and
Framework 1.1 SP1

Would someone please know why we need 2 versions and why the latest one is
not in used? Also if we need to update both the service pack?

I really appreciate your comment and suggestion!!
 
Hi Zeng,

You most likely have the 2002 version of Visual C# which uses framework
1.0.
There are still plenty of .net programs built for framework 1.0 for it to
get a service pack update.

Framework 1.1 is a newer version but sufficiently different that 1.0 is
still needed, and in 2005 there will be version 2.0 that will exist along
with 1.0 and 1.1.

Framework 1.0 SP3 and 1.1 SP1 is an update of their respective versions
and you should probably update them both. Beware that there have been
some issues of programs not working properly after the update.
 
There are 2 major versions of the framework out there 1.0 and 1.1. Each
have their own SP's, but those are not directly relevant to your question.
You probably have VS.NET 2002 and so the applications you build are run
against the 1.0 version of the framework. The 1.1 version is part of XP
SP2.
 
I think I have verified that my vs.net 2002 is using 1.0 to build but how do
I verify if it's the 1.0 is the one that's run against? aspnet_wp.exe is the
one that chooses which version right? In one of my error page, it shows 1.1
in the footer even though my app was built with 1.0 (because I use vs.net
2002 to build)

Any comment? Thanks!
 
I just think of a better question. Since I've been building my web app with
1.0 and running it with 1.1, is there any reason why I should "correct" the
version so that it's running on 1.0 too?

Applications written using VS.NET 2002 only run agains the 1.0 framework
unless you have manually targeted them for the 1.1 framework (which, you
would know if you had done or not).
aspnet_wp.exe is the one that chooses which version right?

No, that is the name of the worker process running your app, but it is not
where the decision is made.
