about .NET versions

[Tony Johansson]

Hello!

I just wonder what do I miss if I only have VS2005 without having
..NET 1.1 installed ?
According to Jon Skeet he said that it makes sense to have both 1.1 and 2.0
installed.
When installing VS2005 you automatically get .NET 2.0 but not .NET 1.1.

What versions of .Net automatically installed when installing VS2005 or
VS2008?

With VS2005 you get .NET 2.0.
With VS2008 you get .NET 3.5.

Remember that 2.0 and 3.5 frameworks include all previous versions too.

>Not really - .NET 2.0 doesn't include .NET 1.1, which has a different
CLR. The framework libraries of .NET 2.0 include all the framework
ibraries of 1.1, but that's not quite the same thing.

>In particular, it makes sense to have both 1.1 and 2.0 installed, but
when you install .NET 3.5 it supercedes .NET 2.0 and .NET

It means that anything built for .NET 1.1 will run under .NET 2.0.
Usually that's fine, but there are a *few* compatibility issues.

According to Jon Skeet he said that it makes sense to have both 1.1 and 2.0
installed.

Sometimes, yes. Only occasionally though.

It also means you can't build anything for anyone *else* to run under
..NET 1.1.

I may be wrong, but couldn't one refrain from using APIs introduced in
2.0, and correct the .exe.config so that 1.x is the required runtime,
even with VS2005?

I don't think so - I'm pretty sure that the IL that it generates says
that it expects the 2.0 CLR. A whole load of extra IL was included in
2.0 for generics etc, and even if you don't use it I expect that it
includes the IL version number.

.NET 1.1.

Which is not a big deal, because .NET 1.1 is not all that widely used. 2.0
is the widely distributed one.

It's certainly less of a big deal now, but quite a few companies have
stayed with .NET 1.1 for a very long time. Hopefully by 2010 we'll be
able to ignore 1.1 completely :)

I would expect a lot of PC's to still be at 1.1. All PC's where .NET
is installed before late 2005 and not upgraded since.

Something to consider:

1.0 was not shipped with any version of Windows
1.1 was shipped with all versions of Windows 2003 (and enabled by
default)
2.0 was shipped with Windows 2003 R2 (but not enabled by default)
3.0 was shipped with Windows Vista and Windows Server 2008 (and
enabled by default)
3.0 is available on Windows Update for XP as optional download
3.5 was not yet shipped with any version of Windows
