)

We recommend that you use this method before you call the [T:Microsoft.SharePoint.Publishing.PublishingWeb.GetPublishingWeb(Microsoft.SharePoint.SPWeb)] method.

Examples

This sample demonstrates setting and saving property values on a publishing Web. Before building and running this sample, verify that Publishing feature has been enabled for the SPWeb, and that the defaultPageFileId is SPFile.UniqueId for the new default page.
