.Net Framework 1.0 v/s 1.1

[Bill]

Having just been prompted to download on my W2k
system .NetFramework 1.1. SP1 and 1.0 SP3 English, I again
wondered why I have two versions of this software.

Trying to re-search this I since read a lot all over about
that software, all mainly very technical in nature, but
nowhere do I find some layman's information re does
version 1.1. replace 1.0 or, if not, what the differences
are and why I need both.

I'm not a developer or techie, so my down to earth
question is:

Do I need both or only the latest 1.1. version, i.e.
can/should I remove via the add/remove function version
1.0?

Thanks.

Hi Bill

I am a developer

There are 2 programs out: Visual Studio.NET 2002 & 2003.

Visual Studio.NET 2002 uses the .NET Framework 1.0 & Visual Studio.NET 2003
uses the .NET Framework 1.1

From a programming point of view. The Framework 1.0 never had a few controls
(Folder Browser Disalog) for example, but the 1.1 Framework does

Also, Microsoft wants everyone (developers) to be using Visual Studio.NET
2003, which means the 1.1 Framework

Also, if you have IIS installed on your machine then you should change it to
the 1.1 Framework

I hope this brief explanation helps

Hi

This will work OK for many application that uses the .Net Framework,
but not all. v1.1 is not 100% backwards compatible with v1.0, and
there are application that will not work unless v1.0 is installed
(even if v1.1 is installed).
