Currently I have installed two (runtime) .NET frameworks on my WinXP system:
v1.1
AND
v2.0
Is this necessary or is v1.1 COMPLETELY included in v2.0 ?
The same questions applies to the relationship between .NET v2.0 and v3.0:
If I install v3.0 can I de-install v2.0?

Yes.

No.

No.
They are completely separate things and either may be used for development
with no connection to the other.

No. Both versions are completely different and 2.0 does not include 1.0

No, different version of .Net are not upward compatible. Higher versions
are not an upgrade. Specific programs require specific versions. Whether
you need all versions depends on whether you have programs that need each
version. So the question comes down to, how did these versions get
installed? Did you install them because a program needed them?

Well, 3.0 is definitely a superset of 2.0, in that 3.0 basically
installs 2.0 and then adds some extra bits. Any application which runs
on 2.0 should run fine on 3.0 too. (I don't know whether if you install
"just" 3.0 it's obvious that you've got 2.0 as well, effectively.)
There are some compatibility issues between 1.1 and 2.0, but many
applications originally written for and testing on 1.1 will run
perfectly well with 2.0.

To run application of .Net 1.1 you must have to have .Net Framework 1.1
installed and it'lll not run under .Net 2.0 so for running 2 applications
belonging to .Net 1.1 and .Net 2.0 you need to have both versions installed
on the machine.
But this time Microsoft kept the Backward compatibility meaning that
applications of .Net 2.0 are 100% compatible and executable under .Net 3.0
withuot needing .Net 2.0 to be explicitly installed.

No, that's not true. .NET 1.1 applications *will* run with only 2.0
installed - there are some incompatibiliti es, but not *very* many. A
lot of 1.1 applications will run perfectly well without any
modifications on 2.0.

Well, it's certainly meant to and I've seen it working myself. I've
also seen it failing due to a few incompatibiliti es, but usually it
works.
And also found on the web that .Net 1.x application is not compatible
and runable on .Net 2.0.
Where exactly?
As I said, there *are* incompatibiliti es, but they should be relatively
rare.
See http://msdn.microsoft.com/msdnmag/is...ut/default.asp

(careful of line wrapping) for an article describing how backwards
compatibility works as well as side-by-side execution. A few quotes:
<quote>
Next in order of importance was that we wanted to ensure that
applications would run properly if only the latest runtime were
installed.
</quote>
<quote>
The result was that the vast majority of applications will not be
impacted by the installation of the .NET Framework 2.0, most
applications will work just fine on machines that only have the latest
version
</quote>
So certainly Microsoft intend it to work - and as I say, I've seen it
work myself.
Indeed, if you run a .NET 1.1 application on a machine with .NET 2.0
installed, it will run with the latest version *by default* unless you
specifically set a flag to run with a particular version.

That site says "on a machine running Windows VistaT with versions 1.1 and
2.0 of the .NET Framework installed, apps built against the .NET Framework
2.0 will run against the 2.0 version, while any older apps will still run
against the 1.1 version." If I'm interpreting that correctly, it seems to
say just the opposite of what you are saying.

Does the .net framework v1.1 come pre-installed on new Window's PC's? For

installed? The article said the PC would have StarOffice installed, which
leads me to believe it will probably have a Sun JVM installed.

what registry entry would i look up to find out if the .net framework 1.1 is

do registry entries know the difference between .net 1.1 and 1.0, my

i'm also asuming that the framework is installed per machine not per user,
is that correct ?
