The interfaces, enumerations and classes in this namespace are held in VirtualRadar.Interface.dll. Virtual Radar Server is loosely coupled (see the remarks against the InterfaceFactory namespace) and almost all of the classes used by the program are private to the library that they live in. They all implement interfaces and the program uses a singleton class factory in InterfaceFactory to resolve references to interfaces when the need arises.

These interfaces are all declared in this library, VirtualRadar.Interface.dll. The library does not contain any of the implementations. It has almost no references to other projects within Virtual Radar Server, aside from InterfaceFactory. Along with the interfaces for the program it also contains the enumerations, custom EventArgs, Exception and Attribute classes that the interfaces refer to. It also contains one or two public helper classes, usually static classes, that the implementations of the interfaces may find useful.
