CS2008 & IIS7.0 - HTTP Error 500.22

I am in the process of installing CS2008 Beta 1 (webinstaller) on my Windows 2008 Server with IIS7.0 & SQL2005.

I get this error when trying to go to the installer or any other page of the cs2008 directory:

HTTP Error 500.22 - Internal Server Error

An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.

Detailed Error Information

Things you can try:

• Migrate the configuration to the system.webServer/modules section. You can do so manually or by using AppCmd from the command line - for example, %SystemRoot%\system32\inetsrv\appcmd migrate config "Default Web Site/". Using AppCmd to migrate your application will enable it to work in Integrated mode, and continue to work in Classic mode and on previous versions of IIS.
• If you are certain that it is OK to ignore this error, it can be disabled by setting system.webServer/validation@validateIntegratedModeConfiguration to false.
• Alternatively, switch the application to a Classic mode application pool - for example, %SystemRoot%\system32\inetsrv\appcmd set app "Default Web Site/" /applicationPool:"Classic .NET AppPool". Only do this if you are unable to migrate your application.

(Set "Default Web Site" and "Classic .NET AppPool" to your application path and application pool name)

You need to follow the last step, this isn't a bug in CS this is a bug with you.

Set the application pool that CS uses to classic mode, not integrated mode.  CS doesn't use integrated pipeline mode

The release of CS 2008 will fully support IIS7 Integrated Pipeline mode. In fact, you can try it now by modfying your web.config according to this blog post: http://www.arcware.net/archive/2008/04/08/Use-a-Single-Web.Config-for-IIS6-and-IIS7.aspx (if you don't modify the web.config, you have to run CS in IIS7 Classic Pipline mode).
