Go to Add-Ins - VSdocman menu or press VSdocman button on standard toolbar. VSdocman dialog appears, select Project Properties pane. Set Miscellanous - Root Namespace page.
This section only applies to Visual Basic because C# doesn't have concept of root namespace. Because root namespace has no source code representation, this dialog is the only place where you can define comment for root namespace.
Root namespace comment
This is XML comment (without comment prefix /// or ''') of root namespace as it would appear in source code.
