Assembly: System.ServiceModel (in system.servicemodel.dll)
There are two constructors used to create an instance of the ServiceHost class. Use the ServiceHost(Type,Uri) constructor which takes the service type as an input parameter, most of the time. The host can use this to create new services as needed. Use the ServiceHost(Object,Uri) constructor instead only when you want the service host to use a specific singleton instance of the service.
