Remarks

NOTE: This class is intentionally *not* placed in the Extensions namespace, but rather alongside the extendee. The extension methods in this class are commonly used, and from the point of view of the developer, can be considered as part of the interface. In addition, this placement allows less namespaces references in typical projects, and better consistency with the COM interfaces (as only methods from this extension class may appear in the COM interfaces).

Other extension classes may exist as well.
