Let's do this right...

The are 2 Contoso services: WidgetManagent (control-plane) and Widget (data-plane)
The RP Namespace is Contoso.Widget

Under data-plane, the folder should be "Widget"
Under resource-manager, the immediate folder is the RP Namespace: "Contoso.Widget"
Under this "Contoso.Widget" folder is the control-plane service name folder: "WidgetManagement"
