ServiceHost Constructor (Object, Uri)
Initializes a new instance of the ServiceHost class with the instance of the service and its base addresses specified.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Use this constructor as an alternative to implementing a custom System.ServiceModel.Dispatcher.IInstanceContextInitializer when you want to provide a specific object instance for use by a singleton service. You may want to use this overload when your service implementation type is difficult to construct (for example, if it does not implement a default public constructor that has no parameters).
Note that when an object is provided to this overload, some features related to the Windows Communication Foundation (WCF) instancing behavior work differently. For example, calling InstanceContext.ReleaseServiceInstance have no effect when a well-known object instance is provided using this constructor overload. Similarly, any other instance release mechanism is ignored. The ServiceHost always behaves as if the OperationBehaviorAttribute.ReleaseInstanceMode property is set to ReleaseInstanceMode.None for all operations.
