The anonymous namespace doesn't have any parent namespace. If the namespace AA.BB doesn't contain any type, it is not shown as a parent namespace of AA.BB.CC. Indeed, if a namespace doesn't contain any type, the NDepend code model doesn't contain an associated INamespace object. This property getter has a O(this.ParentAssembly.ChildNamespaces.Count) time complexity.
