Framework 1.1 upgrade and ISAPI Filter Change Not Working

P: n/a
Hi there,

We recently upgraded to the 1.1 framework, and of course,
all of our 1.0 asp.net apps starting using the 1.1
framework, which we didn't want to happen.

I found an MS article saying if you modify the ISAPI
filter setting in IIS for the site to point to the 1.0
aspnet_filter.dll, your app will then use the 1.0
framework.

(see http://msdn.microsoft.com/library/default.asp?
url=/library/en-us/dnnetdep/html/sidexsidenet.asp,
the "configuring web apps" section)
However, after I do this it still continues to use the
1.1 framework, it doesn't seem to care what is set in the
ISAPI filter tab of IIS.

My workaround is to go into IIS admin, to the "home
Directory" tab and then click on "configuration".

On the "App Mappings" tab I set everything that is
pointing to asp_isapi.dll for 1.1 to the 1.0 version of
it, and after that everything seems to work fine.
Anyone have any idea why the isapi mapping isn't making
my web app use the 1.0 framework? Everything I've seen
in documentation says this should do the trick. It would
be a real pain to have to change everything in the "app
mappings" tab for all the sites I want to use the 1.0
framework.

Thanks

This article may help to answer some questions.

"ASP.NET Side-by-Side Execution of .NET Framework 1.0 and 1.1"
http://www.asp.net/faq/SideBySide.aspx

I have read it and it seems to address some of these issues.
HTH.
