We are trying to deploy our web application written in .net 4.0 onto iis6 and keep getting the Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive Parser error. We have used the aspnet_regiis.exe -iru command to install 4.0 on iis and restart it, seperated the application pools, set the website to use asp.net version 4.0.30319. It keeps throwing the configuration error.
Any ideas?
