If the PFN_WEB_CORE_ACTIVATE function returns an ERROR_INVALID_DATA message, the Event Viewer may contain additional details regarding the cause of the failure.

The PFN_WEB_CORE_ACTIVATE function is a prototype for the WebCoreActivate DLL entry point in Hwebcore.dll that is used to start the Hosted Web Core. The process that hosts the Web core is required to provide the path of a configuration file that contains the configuration settings for any sites, the application pool, and so on, that are to be created.

System_CAPS_ICON_note.jpg Note

The Hosted Web Core requires a configuration file that follows the design of the ApplicationHost.config file, except that Hosted Web Core supports only one application pool. For more information about how to create a configuration file for your application, see Walkthrough: Creating a Configuration File for Hosted Web Core.

This function also requires the name of the instance of the Hosted Web Core that IIS 7 uses when it logs events to the Event Viewer. The hosting process may optionally provide the path of a root Web.config file that contains any additional parameters.
