Vista - Versions - Explanation

Hi

I have to explain why we should have more than one version of the .Net
Framework installed onto our Computers.

From my understanding, certain applications will insist on certain
functions, can anybody add any ideas to this.

Regards

That reason sounds fine to me, especially if I care about an application
that needs on eof those functions.

I don't know how this flies at your company, but the number of .net versions
on most computers in our shop is almost always less than the number of JRE
versions.

I think it just depends on context.

It's my opinion that generally speaking, one should just use the most
recent .NET version when possible.

But, there are subtle differences between versions that can affect whether
an application will work or not. In the vast majority of cases, these
differences are never a problem. But if you're in a situation where you
simply cannot afford taking that risk, it may be better to maintain
multiple versions installed to avoid that issue.

Note that even if you run an application targeting an earlier version, but
using a more recent version, the developer of the application should
definitely review the changes from one version to the next, especially
those Microsoft documents as "breaking changes", so that they can have
some confidence as to whether or not a version change will actually affect
the code they've written.

What about VSTO applications, they always need to have a certain version
installed?

The fact is, applications can be configured (to a certain extent) to
require a specific .NET version. Such applications simply won't even run
if the correct version isn't present. You have no choice about those.

I assumed you were talking about the applications that were written with a
specific version in mind (e.g. simply because that was the current version
when the application was written), but which _could_ run on other
versions. There's no point in asking whether you should keep other .NET
versions around for applications that _require_ those other versions;
obviously, if you want to run those kinds of applications, you have no
choice in the matter.

D,

It was intentioned to use one Net version by making it upwards compatible.

A very little bit went wrong between 1.1 and 2.0, where some slight methods
within those are not working completely the same.

That is why beside the latest it is clever to install the version 1.1 as
well.

2.0, 3.0 and 3.5 are working all upwards compatible.
(this is the same within 1.0 and 1.1)
