How to: Publish Metadata for a Service Using Code 

You can publish metadata for a service in two ways: declaratively in a configuration file or imperatively in code. This topic shows you how to publish metadata in code.

To publish metadata in code

1. Instantiate a ServiceHost object by passing in the service type and the base address:

   C#

   Copy Code

   ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService), baseAddress);
   

2. Check to see whether the service host already contains a ServiceMetadataBehavior and, if so, set HttpGetEnabled to true and HttpGetUrl to an appropriate URL. If the service host does not already have a ServiceMetadataBehavior, set the appropriate properties and add the ServiceMetadataBehavior to the service host's behaviors collection:

   C#

   Copy Code

   ServiceMetadataBehavior smb = serviceHost.Description.Behaviors.Find<ServiceMetadataBehavior>();
   if (smb != null)
   {
       smb.HttpGetEnabled = true;
       smb.HttpGetUrl = mexAddress;
   }
   else
   {
       smb = new ServiceMetadataBehavior();
       smb.HttpGetEnabled = true;
       smb.HttpGetUrl = mexAddress;
       serviceHost.Description.Behaviors.Add(smb);
   }
   

3. Add the metadata exchange endpoint:

   C#

   Copy Code

   ServiceEndpoint se = serviceHost.AddServiceEndpoint(typeof(IMetadataExchange), new WSHttpBinding(), mexAddress);
   

4. Use Internet Explorer to browse to the base address of the service and verify that the metadata publishing has been turned on. If not, you will see a message at the top of the resulting page that says: "Metadata publishing for this service is currently disabled."
