CLR 1.1 and 2.0 (beta) on same machine?

[jpuopolo]

All:

I have a SINGLE laptop currently running Windows 2000 Pro (don't ask -
WinXP killed my machine at one point) and the NET Framework 1.1. I
would like to start playing with the 2.0 (beta) framework. The big
question is... Will they both run on the same computer w/o clobbering
one another?

Thanks,
John

Yes, they can both run in side-by-side mode BUT:

Your 1.1 projects will now run under the 2.0 Framework (and perhaps
incorrectly).
AND
It is NEVER a good idea to install beta software on a machine that you care
at all about.

Not true, projects compiled with the 1.1 Framework still use the 1.1 Framework , not 2.0. I currently have VS.NET 2002, VS.NET
2003 & VS2005 (Beta1) all installed on the same machine, and so far have had no issues with any project trying to run with the
wrong Framework. I do suggest that you should make a good back up of your drive BEFORE installing VS2005 & the 2.0 Framework.
There is no guarantee that Beta1 will uninstall completely. However, I have found a way to get rid of it completely without
trashing the rest of the system. ( found on one of the MS newsgroups...........works too,)
Which I have tested by uninstalling VS2005 & 2.0 Framework and did not have any ill effects.
But, for safety's sake, it is a better idea to run VS2005 & 2.0 Framwork using a VM or a seperate OS on another system that is
not your main system.

Very true! I had 2003 and 2005 installed and the 2003 projects would no
longer run (or even open in 2003 for that matter) on the 1.1 Framework
unless specifically targeted to it. And, I'm not talking about 2003
projects that were opened (and promoted) to 2005 projects, I'm talking about
2003 projects not even opening under 2003 any longer. As soon as I
uninstalled 2005, my 2003 projects worked as normal again. I am not the
only one that experienced this either, this NG has had many posts about it.
Just because you haven't experienced any issues, does not mean that there
aren't any issues. It's beta software after all.
