, NET Framework backward compatibility

[ajg047]

I recently installed ,NET Framework 3.0
Question - does it contain all the features of framework version 1 and 2? Or
do I have to keep all three on my computer. I'd prefer to just have the
latest.

Hello ajg047,

I recently installed ,NET Framework 3.0
Question - does it contain all the features of framework version 1 and
2? Or
do I have to keep all three on my computer. I'd prefer to just have
the
latest.

There is no guarantee all applications developed on 1.0 or 1.1 will work
under the latest framework. They should. But as I said, no guarantee.

Framework 3.0 is an add-on to 2.0, so you cannot uninstall 2.0 if you want
to have 3.0.

Thanks. The issue I'm having is my computer refuses to install a security
update for .NET 2 (KB928365) ... get error code 0X64C. Found no info so far
how to resolve it.

Deinstall Frameworks 2.0 and 3.0. Reboot. Then reinstall Framework 2.0.
Apply all security patches. Install Framework 3.0 - it's installer detects
2.0 and doesn't reinstall 2.0.
