If I install Microsoft .NET Framework 3.0,...

by Paul C / December 15, 2007 5:44 PM PST

...need I keep older versions on my PC or can I uninstall them? I wouldn't see why they'd be needed, but a friend says that I should leave them there.

TIA, Paul

Depends

.NET Frameworks 1.0, 1.1, and 2.0 were all cumulative and self contained. Then I stopped paying attention, and apparently .NET Framework 3.0 marked the beginning of the supplemental versions that build on 2.0 and require 2.0 to remain installed. I only assume .NET Framework 3.5 will be the same way.

So you shouldn't need any of the 1.x series installed, but you will need 2.0. Though some people seem to claim that older .NET apps written for the 1.x series don't always work well on 2.0. Last I checked Microsoft was still offering the .NET Framework 1.1 download via Windows Update, so it'd just a small additional hassle to reinstall it if you remove it and run into one of these apps I suppose.

What does Microsoft.Net framework actually do?

I have a lot of disrespect for MegaloShaft's `we're here to make your job easier' assurances on upgrades and patches, but I can't find any information on exactly what MS.NET Framework is supposed to do, much less convincing arguments for why I should take in an "improved" version -(and I see plenty of grumbling on how hard it is to fix operation after download). So...what does this `fix/upgrade' do, and why should (or shouldn't) I let it?

In one sentence -> Net 1.0 is not superseded or replaced by Net 3.0.

Many are amazed over this as well as I that Microsoft didn't clarify that you keep the Net 1.0 if you run Net 1.0 apps, keep the Net 2.0 if you run Net 2.0 apps, and so on.

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
