.Net Market penetration

[milener]

I also posted this on one other forum ,sorry if I am doubling up here.
not sure of the reader-ovelap between groups. THis may not be the
right forum for market questions, I'm looking for
an active set of .Net / C# folks to help us locate the right
information

I'm looking for the following, :
- % of Windows clients that have .Net 1.1 or later installed as of
March 2006.
- What OS did .Net first appear in, preinstalled
- Does .Net come with IE and if so, starting at what version of IE
- If you write in .Net 1.1, will that code excute error free in 2.0,
and vice-versa, can 2.0 .Net execute in 1.1 framework (obviously
assuming you use classes that are avail in 1.1)?

Obviously, the question behind the question is - Can we ship a C#
client and trust that enoguh Windows clients out there today have .Net
preinstalled?

If anyone can point me in the right direction to who or where to get
answers to these questions, I'd very much appreciate it!

- % of Windows clients that have .Net 1.1 or later installed as of

March 2006.

Irrelevant, in the context of your actual question. The .Net platform can be
installed *with* any software that needs it.

- What OS did .Net first appear in, preinstalled

See my answer to the first question.

- Does .Net come with IE and if so, starting at what version of IE

No. IE is part of the Windows operating system.

- If you write in .Net 1.1, will that code excute error free in 2.0,
and vice-versa, can 2.0 .Net execute in 1.1 framework (obviously
assuming you use classes that are avail in 1.1)?

..Net is specific about what versions of what assemblies are used. You can
have many different versions of various .Net assemblies installed. As long
as the version that a given app needs is installed, the app will run. The
app will not run without it.

Obviously, the question behind the question is - Can we ship a C#
client and trust that enoguh Windows clients out there today have .Net
preinstalled?

As long as you include the version of the .Net platform that is needed by
the application, in the installation, no problemo. That is, of course,
unless the OS is Windows 98/NT4 or below.
