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 class. In addition, this placement allows fewer 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.

This class contains extension methods (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.
