I am attempting to run an application in IIS8 that has the following in the config:
<modules runAllManagedModulesForAllRequests="true" />
IIS8 is giving me an error that says...
This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
I'm guessing by the error and a quick SO search that there is some higher level security setting that's preventing that line from being allowed. Any ideas?
I've solved the same problem by installing the window features "Internet Information Service/World Wide Web Service/Application Development/ASP.NET x.x" in the Control Panel of Windows8. If you want to setting on Windows Server 2012, the following link gives you hint. http://www.iis.net/learn/get-started/whats-new-in-iis-8/iis-80-using-aspnet-35-and-aspnet-45
hope that it works out.
