The Namespaces page in the project properties lets you add or update namespaces for your managed COBOL project, or specify paths to referenced assemblies.
Note: The following settings apply to managed projects only.
Add namespace
Enables you to add namespaces to the project. This is equivalent to the ILUSING compiler directive.
Enables you to specify a different name for an imported namespace.
Reference Paths
Specify the paths to the locations of the assemblies containing classes that are used by the project.
