Remarks

IWorkspaceExtensionManageris an optional interface supported by Personal, File and ArcSDE geodatabase workspaces. The FindExtensionmethod returns a reference to a workspace extension given its GUID. An application can also discover and iterate over all extensions using the ExtensionCountand Extensionproperties.

The following code demonstrates how to get a reference to the IWorkspaceExtensionManager in order to access the IDatasetContainer2.  The end result of which could be to create a network dataset or find a pre-existing network dataset.  The code assumes you have a reference to the workspace (workspace) in which the network dataset will be created or exists.  The workspace could also correspond to the folder containing a shapefile network dataset or SDC data.
