Provides a handler for responding to Web site creation.
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
Be careful about calling the ApplyWebTemplate method within a Web site provisioning callback. Calling this method inside a provisioning callback that is defined within the same site definition configuration that is being applied can cause an infinite loop. Instead, create two similar site definition configurations within the site definition, one that is visible and one that is hidden. The configuration can then contain a provisioning assembly callback that applies the hidden configuration to Web sites.
