Points To Watch

■ In the feature source XML, the provider name (for example, OSGeo.SDF.3.3)

must match one of the provider names listed in the output of 

MgFeatureService.GetFeatureProviders() .

■ In the layer definition, the ResourceId value must match the path of the

feature source. In the example above, this path is used in the layer

definition:

<ResourceId>Library://Data/SDF/Zoning.FeatureSource

</ResourceId>

So the corresponding path must be used when the feature source is created.

For example:

MgResourceIdentifier rID_feature_source =

new MgResourceIdentifier(@"Library://Data/SDF/Zoning.FeatureSource");

■ Create new layers using the static method AcMapLayer.Create() .

■ Create new layer groups using the AcMapLayerGroup constructor

AcMapLayerGroup(groupName) .
