.NET Framework Class Library
ServiceHost Class

Provides a host for services.

Namespace:  System.ServiceModel
Assembly:  System.ServiceModel (in System.ServiceModel.dll)
Syntax

Visual Basic (Declaration)
Public Class ServiceHost _
    Inherits ServiceHostBase
Visual Basic (Usage)
Dim instance As ServiceHost
C#
public class ServiceHost : ServiceHostBase
Visual C++
public ref class ServiceHost : public ServiceHostBase
JScript
public class ServiceHost extends ServiceHostBase
Remarks

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.

Examples

Visual Basic
' 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

Redundant code in example
The C# example here has lots of redundant and unused code. Please update it! If needed, maybe it could be split into two examples.
