Re: ASP.Net 1.1 and 2.0 Coexist?

I'll be a horse's *ss.

I wasn't about to wipe a partition and install W2K/IIS 5,
so I did the next best thing in a second dev box I have :

I ran IIS 6 in IIS 5 isolation mode and, you're right, changing the isolation
mode doesn't affect the concurrent running of 1.1 apps and 2.0 apps,
which is diametrically opposed to what the behavior of IIS 6 is, in which
if you don't isolate 1.1 and 2.0 apps in different Application Pools,
the response will be the error message "The Application is Unavailable".

Thanks for pointing this out to me.
( I need more more boxes to run older OS's... )
