re:
I am wondering can I run asp.net 1.1 web apps
and asp.net 2.0 web apps on the same box?
No problem at all.
Just make sure they are running isolated from each other.
1.1 and 2.0 apps must run in different processes.
If you're running IIS 6.0, create a new Application Pool for your 2.0 apps.
Use the IIS Manager, and scroll down to "Application Pools".
You can assign the App to the Application Pool you created in the
Virtual Directory tab of the website's properties in the IIS Manager.
You can create as many App Pools as you want, but be aware that
each Application Pool means at least another 30-40MB ram minimum.
If you're running IIS 5.0/5.1, run your 2.0 apps either in "High Isolation",
isolated from each other *and* 1.1 apps, or in "Medium Isolation",
with all 2.0 apps pooled in one process.
You can choose High (Isolated) or Medium (Pooled) from the
Application Protection drop-down list on the Home Directory
or Virtual Directory property sheet in the IIS Manager, in IIS 5.0/5.1.
re:
If possible how does the web server realize what framework to
use when calling up a particular web app?
By assigning it to the proper .Net Framework version in the
ASP.NET tab in the website's "properties" in the IIS Manager.
re;
Is there any settings that I have to be aware
of to make sure one doesn't step on the other?
What I explain in this post is all you need to do.
re:
Also is it possible on a dev box to have Sql server 2000
and Sql server 2005 running on the same box?
I know that SQL Server 2000 and SQL Server Express 2005 can coexist.
I don't know whether SQL Server 2000 and SQL Server 2005 can coexist.
You might want to ask that question in the SQL Server newsgroups.
