The Namespaces page in the project properties lets you add or update namespaces for your .NET COBOL project, or specify paths to referenced assemblies.
Note: The following settings apply to .NET COBOL 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.
