Examples

// Host the service within this EXE console application.
public static void Main()
{
  using (ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService)))
  {
    try
    {
      // Open the ServiceHost to start listening for messages.
      serviceHost.Open();

        // The service can now be accessed.
      Console.WriteLine("The service is ready.");
      Console.WriteLine("Press <ENTER> to terminate service.");
      Console.ReadLine();

      // Close the ServiceHost.
      serviceHost.Close();
    }
    catch (TimeoutException timeProblem)
    {
      Console.WriteLine(timeProblem.Message);
      Console.ReadLine();
    }
    catch (CommunicationException commProblem)
    {
      Console.WriteLine(commProblem.Message);
      Console.ReadLine();
    }
  }
}
' 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

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.

Constructors

ServiceHost()

Initializes a new instance of the ServiceHost class.

ServiceHost(Object, Uri[])

Initializes a new instance of the ServiceHost class with the instance of the service and its base addresses specified.

ServiceHost(Type, Uri[])

Initializes a new instance of the ServiceHost class with the type of service and its base addresses specified.

Properties

SingletonInstance

Gets the singleton instance of the hosted service.

Methods

AddServiceEndpoint(Type, Binding, String)

Adds a service endpoint to the hosted service with a specified contract, binding, and endpoint address.

AddServiceEndpoint(Type, Binding, Uri)

Adds a service endpoint to the hosted service with a specified contract, binding, and URI that contains the endpoint address.

AddServiceEndpoint(Type, Binding, String, Uri)

Adds a service endpoint to the hosted service with a specified contract, binding, an endpoint address, and a URI on which the service listens.

AddServiceEndpoint(Type, Binding, Uri, Uri)

Adds a service endpoint to the hosted service with a specified contract, binding, a URI that contains the endpoint address, and a URI on which the service listens.

ApplyConfiguration()

Loads the service description from the configuration file and applies it to the runtime being constructed.

CreateDescription(IDictionary<String,ContractDescription>)

Creates a description of the service hosted.

InitializeDescription(Object, UriSchemeKeyedCollection)

Initializes a description of the service hosted based on its instance and specified base addresses.

InitializeDescription(Type, UriSchemeKeyedCollection)

Initializes a description of the service hosted based on its type and specified base addresses.

OnClosed()

Disposes of disposable services that are being hosted when the service host is closed.
