.NET 3.5 install questions

On our server we have .NET 1.0, 1.1 and 2.0 ASP.NET websites.

I am creating a .NET 3.5 website.

If my network guy installs the 3.5 FW, will the older apps still run ok?

Is 3.5 fully backwards compatible with 1.0, 1.1 and 2.0 ASP.NET web apps?

Thanks!

Yes.

That's not quite how it works. Installing .NET 3.5 doesn't overwrite or
uninstall the previous versions - they all co-exist quite happily, as you
will be able to tell from the folder structure.

The older apps won't care about any other version of the framework than the
one for which they were compiled...

The main point of contention is extra stuff added on top.

If you are using AJAX, for example, you might have some problems until you
ujpdate your web.config. The 2.0 bits will be pointed to a version 1.06.###
(forget the entire number), while the 3.5 bits point to 3.5.0.0 version. If
you change version in the web.config, you should be fine.

That is your biggest danger, from my experience.

Thanks. So .NET 3.5 will install side by side with older frameworks
installed on the server?

Hello, What is the best way to install a python application under Unix. Since python modules are platform independent I would guess these should be placed under an application specific directory under either /usr/share or /usr/local/share with a corresponding link to the main module(s) under /usr/bin or /usr/local/bin for user applications and /usr/sbin or /usr/local/sbin for system applications. Assuming this is done, should .pyc and...

For most users, this new feature is actually very convenient. If you want to control the update process,...
