ServiceHost Class
Provides a host for services.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Implements the host used by the Windows Communication Foundation (WCF) service model programming model.
Use the ServiceHost class to configure and expose a service for use by client applications when you are not using Internet Information Services (IIS) or Windows Activation Services (WAS) to expose a service. Both IIS and WAS interact with a ServiceHost object on your behalf.
To expose a service for use by callers, WCF requires a complete service description (represented by the ServiceDescription class). The ServiceHost class creates a ServiceDescription from the service type and configuration information and then uses that description to create ChannelDispatcher objects for each endpoint in the description.
Use a ServiceHost object to load a service, configure endpoints, apply security settings, and start listeners to handle incoming requests.
' Host the service within this EXE console application. Public Shared Sub Main() ' Create a ServiceHost for the CalculatorService type and use the base address from config. Using svcHost As New ServiceHost(GetType(CalculatorService)) Try ' Open the ServiceHost to start listening for messages. svcHost.Open() ' The service can now be accessed. Console.WriteLine("The service is ready.") Console.WriteLine("Press <ENTER> to terminate service.") Console.WriteLine() Console.ReadLine() 'Close the ServiceHost. svcHost.Close() Catch timeout As TimeoutException Console.WriteLine(timeout.Message) Console.ReadLine() Catch commException As CommunicationException Console.WriteLine(commException.Message) Console.ReadLine() End Try End Using End Sub
