Which version?

[Linn Kubler]

Hi,

I was just wondering, do I need to have both versions of .NET installed on
my computer? I see there is Version 1.1 and Version 2.0, does 2.0 include
all the functionallity of 1.1?

Please advise,
Linn

Pretty much.

*Most* .NET 1.1 applications wil run happily (sometimes better) under .NET
2.0. However, there are some changes in .NET 2.0 that cause issues. The
best bet is to install both for general work but test your programs in a
situation with both together and both individually.

That is, unless you are developing for .NET 2.0 in which case testing with
just .NET 1.1 would be silly. ;-)

Yeah, we're not doing development this is just for general users. I don't
even know that we are using any .NET applications but think it prudent to
have it installed. Sounds like I could get away with just running 2.0
unless I run into a problem. Is that correct?

Thanks,
Linn

No matter what system in the world you are running, as long there are
not problems, it's fine ;-).

Concerning .NET: Yes, I normally only install the 2.0 Version and
never ran into 1.1 or 1.0 backward compatibility issues.

Linn,

In addition to the others who wrote "there are some issues". As long that
there is not a Service Pack for Net 2.0, than it is in my idea better to use
both versions.

Just my thought,

I've run into a few. There are some pretty interesting ones lurking
around. Three that I've run into:

1) Different handling of boxed out/ref parameters with reflection
2) Different regex handling in some situations
3) Something about cryptography, but I can't remember the details

(None of these are listed on the MS compatibility page, btw...)

You can pretty much bet that for any incompatibility I run into,
there'll be several (a hundred?) others...

I'd say that even if there's a service pack, there will be some
incompatibilities. In some cases there's logically incorrect behaviour
which has been fixed in 2.0, but which will break some 1.1 apps... I
wouldn't expect a service pack to reverse that kind of decision.
