1.http-get WCF Mode

Provide metadata by means of HTTP

1.1. How to configure Files

<System.ServiceModel>  <Services>    <Servicename= "MyService"behaviorconfiguration= "Mexget">      <Host>        <baseaddresses>          <Addbaseaddress= "Http://localhost:8000/"/>        </baseaddresses>      </Host>      ...    </Service>    <Servicename= "Myotherservice"behaviorconfiguration= "Mexget">      <Host>        <baseaddresses>          <Addbaseaddress= "http://localhost:8001/"/>        </baseaddresses>      </Host>      ...    </Service>  </Services>  <Behaviors>    <servicebehaviors>      <Behaviorname= "Mexget">        <Servicemetadatahttpgetenabled= "true"/>      </Behavior>    </servicebehaviors>  </Behaviors></System.ServiceModel>

In general, the base site of HTTP can access metadata, or you can specify a different address:

<= "Mexget">  <= "true"  = "mymexaddress"/></behavior>

1.2. Code mode

ServiceHost host =NewServiceHost (typeof(MyService)); ServiceMetadataBehavior Metadatabehavior;metadatabehavior= host. Description.behaviors.find<servicemetadatabehavior>();if(Metadatabehavior = =NULL) {Debug.Assert (Baseaddresses.any (baseaddress=>baseaddress.uri.scheme = ="http")); Metadatabehavior=NewServiceMetadataBehavior (); metadatabehavior.httpgetenabled=true; host. DESCRIPTION.BEHAVIORS.ADD (Metadatabehavior);} Host. Open ();

2.Metadata Exchange Endpoint

Platform-independent metadata exchange that supports multiple protocols

<Services>  <Servicename= "MyService"behaviorconfiguration= "MEX">    <Host>      <baseaddresses>        <Addbaseaddress= "net.tcp://localhost:8001/"/>        <Addbaseaddress= "net.pipe://localhost/"/>      </baseaddresses>    </Host>    <EndpointAddress= "MEX"binding= "Mextcpbinding"Contract= "IMetadataExchange"/>    <EndpointAddress= "MEX"binding= "Mexnamedpipebinding"Contract= "IMetadataExchange"/>    <EndpointAddress= "Http://localhost:8000/MEX"binding= "mexHttpBinding"Contract= "IMetadataExchange"/>    ...  </Service></Services><Behaviors>  <servicebehaviors>    <Behaviorname= "MEX">      <Servicemetadata/>    </Behavior>  </servicebehaviors></Behaviors>
