IIS settings now live in ApplicationHost.config

Can also be specified in web.config if delegation is allowed

All settings are schematized in XML‘Schema’ files live in %windir%\system32\inetsrv\config\schema

Shared configuration allows multiple servers to use the same centralized configurationExtending configuration

Static ConfigurationDrop a .xml file into the schema directoryAdd a section to applicationHost.config

Allows you to add dynamic properties and add behavior to configurationAHADMIN - Application Host Administration Interface

Implemented in %Windows%\System32\Inetsrv\nativerd.dllImplements IIS native configuration stackExposes a COM API

Exposes three interfaces for Dynamic Extensibility
