Visual Basic® 2010 Unleashed

No Constructor

As previously mentioned, modules can be considered as shared classes, although Visual Basic provides support for classes with only shared members but not direct support for shared classes. Because of their shared nature, as a general rule modules do not support the constructor (Sub New). An exception is that you can declare a Sub New in a module that will be private and any code in the private constructor will be executed the first time any call to the module is made.
