A container for describing this network dataset's feature dataset extension properties.
NetworkDatasetFDExtension is a non-creatable object. References to non-creatable objects must be obtained through other objects.
The NetworkDatasetFDExtension object contains members that facilitate the creation and browsing of network datasets inside of a geodatabase feature dataset. The IDatasetContainer2 interface contains the CreateDataset method which should be used to create network datasets with a populated data element.
| Interfaces | Description | 
|---|---|
| IDatasetContainer2 | Provides access to members that return datasets by name, ID and index. | 
| IDatasetContainer3 | Provides access to members that return datasets by name, ID and index. | 
| IDatasetEdit | Provides access to information about the status of datasets being edited. | 
| IFeatureDatasetExtension | Provides access to standard functionality found in all feature dataset extensions. |
