true if the WSDL is published; otherwise, false. The default is false.
Examples
The following code example demonstrates the use of ServiceMetadataBehavior in a configuration file to enable metadata support for HTTP/GET and WS-Transfer/GET requests.
// Create a new metadata behavior object and set its properties to
// create a secure endpoint.
ServiceMetadataBehavior sb = new ServiceMetadataBehavior();
//sb.EnableHelpPage= true;
//sb.HttpsGetUrl = new Uri("https://myMachineName:8036/myEndpoint");
//myServiceHost.Description.Behaviors.Add(sb);
}
private void SnippetServiceMetadataBehavior()
{
// service for which <<indigo2>> automatically adds a
// ServiceMetadataBehavior to publish metadata as well as
// an HTML service help page
// from C_HowToSecureEndpoint\cs
// Create a new metadata behavior object and set its properties to
// create a secure endpoint.
ServiceMetadataBehavior sb = new ServiceMetadataBehavior();
/* sb.EnableHelpPage = true;
sb.enableMetadataExchange = true;
sb.HttpsGetUrl = new Uri("https://myMachineName:8036/myEndpoint");
myServiceHost.Description.Behaviors.Add(sb);
*/
}
private void Run()
{
// T:System.ServiceModel.ServiceMetadataBehavior
// <Snippet#0>
// Create a ServiceHost for the service type and use the base address from configuration.
ServiceHost host = new ServiceHost(typeof(SampleService));
try
{
ServiceMetadataBehavior metad
= host.Description.Behaviors.Find<ServiceMetadataBehavior>();
if (metad == null)
metad = new ServiceMetadataBehavior();
metad.HttpGetEnabled = true;
host.Description.Behaviors.Add(metad);
host.AddServiceEndpoint(
ServiceMetadataBehavior.MexContractName,
MetadataExchangeBindings.CreateMexHttpBinding(),
"mex"
);
// 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 ServiceHostBase to shutdown the service.
host.Close();
// </Snippet#0>
Remarks
If the value of HttpGetUrl is relative, the address at which the metadata is published is the base address and the service address plus a ?wsdl querystring.
If the value of HttpGetUrl is absolute the address at which the metadata is published is the value of HttpGetUrl value plus a ?wsdl querystring.
For example, if the service address is http://localhost:8080/CalculatorService and the HttpGetUrl is an empty string, the HTTP/GET metadata address is http://localhost:8080/CalculatorService?wsdl.
If you do not enable this property and do not change HttpGetUrl or set it to a relative address, an exception is thrown at runtime when the service host is opened without a base address for HTTP.
