Prev: SQL fails to start after install .net 3.5
Next: COM error in IIS7
From: Aled G on 3 Jan 2008 10:48
Hi,

After upgrading to .net 3.5, my web app is giving the error on
all .aspx pages:

" Method not found: 'System.Security.NamedPermissionSet
System.Web.HttpRuntime.GetNamedPermissionSet()' "

....on an app which worked just fine before.

This is on XP SP2, IIS 5.1. Have tried aspnet_regiis -i, reinstalling
IIS, and reinstalling the .net framework.

Stack trace and event log entry below.

At a loss what to do next - don't want to reinstall everything as this
is my development workstation. Any further suggestions welcome.

Cheers,
A.
