I Have Microsoft .NET Frameworks; 3.0, 2.0, 1.1. Which can I delete?

Do I need these 3 Microsoft .NET Frameworks?

I would probably keep 3.0, so would I still need 2.0 & 1.1?

 

I imagine an application installed with 1.1. If that is the case, you'll probably need to keep it. However, I believe applications coded with 2.0 will work with 3.0 installed. I am not sure if that is right, though.

 

You probably dont need the 1.1 and 2.0 if you have 3.0

 

You don't need 2.0 if you have 3.0, it has everything 2.0 had within it. Probably the same case with 1.1, so I guess you can uninstall them.

 

I don't know if that is the case. If it was, why would some applications requiring 1.1 not work with 2.0 installed? I believe you are right about 2.0 apps working on 3.0, but not 1.1.

 

Uninstall 1.1 and 2.0 keep 3.0. The new ones have the updated code from the old ones, so no need for the old.

 

uhm, uninstall all, then install net framework 3.5

3.5 will then install all relevent code (including parts of framework 2.0 that are not duplicated in the 3.x code

You don't really need to uninstall any of it, really...net framework will just skip over whatever is already installed. However, I have run into several dozen machines that had corrupted net framework installations on them (you will see errors in the event viewer if this is the case)

UNinstalling everything and starting from scratch seemed to lend itself to a smoother running machine

 

Don't uninstall anything. When you install 3.5, even on a fresh system, you automatically get the older versions as well as they are all needed.

 

I believe that there are some upward incompatibilities; however, if you are running .net applications, you already know about incompatibilities.

 

If you have an application that requires V1.1, it will NOT work with V2 or V3. You will need 1.1, v2 is NOT backward compatible, unfortunately. I have a commercial app the we wrote to use v1.1, the installer refuses to install the app on a system that has only v2 on it.

Will Windows actually allow you to uninstall an older framework without uninstalling the newer one first? I thought the .NET frameworks were all built on top of each other, which would be why if you install .NET 3.5 you will automatically get all the previous ones installed as well.

 

.NET 1.1 uses different runtime engine as .NET 2.0, 3.0, 3.5.
So keep 1.1 and 3.0/3.5

 

I agree not to delete any. Some softwares are specific to a version.

 

But he wants to delete some to save disk space.

 

And if he does so, some applications installed are likely to break. The only reason he has all of them in the first place is he either installed some apps that required each of those versions OR he installed all of them himself. If the latter he can delete any of them. If the former, he does so at the peril of the app in question going belly up.

Sadly, they are NOT backward compatible. An app that needs V1.1, needs V1.1 it will not recognize and use any other version.

I completely agree with ScuderiaConchiglia. I have some apps written in v1.1 which do not install on a system with no v1.1 and only later versions !!

 

I would just leave it alone.

 

I'm confuzzeld.

From what I have extracted, it sounds like:

Must keep 1.1; upgrade from 2.0 to 3.0

So I keep 1.1 & 3.0

???

 

Just keep all of them. As mentioned before, if you didn't manually install a specific version, a program that needs it did.

Anyways, are you trying to gain disk space or something? I don't think you'd see much of an increase in HDD space by uninstalling a a version of .NET Framework. There are other, more effective ways of deleting unnecessary files and regaining hard drive space.

It just seems like you're going to go through a lot of trouble for little to no benefit to you.
