配置AJAX Enabled WCF在hosting时: Showing the serviceMetadata in an ASP.NET AJAX Service

Here's an example of configuring a web.config file to show the meta data for an ASP.NET 3.5 AJAX WCF service.

In this case, you first add the service using Add New Item -> AJAX-Enabled WCF Service -> (Name WeatherService.svc) -> Add.

Next, configure the web.config's <system.serviceModel> section to look like this:

<system.serviceModel>
<services>
<service name="WeatherService"
behaviorConfiguration="WeatherServiceAspNetAjaxBehavior">
<endpoint address=""
binding="webHttpBinding" contract="WeatherService" />
<endpoint contract="IMetadataExchange"
binding="mexHttpBinding" address="mex" />
</service>
</services>
<behaviors>
<endpointBehaviors>
<behavior name="WeatherServiceAspNetAjaxBehavior">
<enableWebScript />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="WeatherServiceAspNetAjaxBehavior" >
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
</system.serviceModel>

 使得：

endpointBehaviors  &serviceBehaviors　共用一个名字。

 或者如下：

<behaviors>
      <endpointBehaviors>
        <behavior name="AjaxBehavior">
          <enableWebScript />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="AjaxServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
 
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
    
    <services>
      <service behaviorConfiguration="AjaxServiceBehavior" name="ShoppingCartService">
        <endpoint address="" behaviorConfiguration="AjaxBehavior"
                  binding="webHttpBinding" bindingConfiguration="AjaxBinding"
                  contract="ShoppingCartService" />
        <endpoint address="" behaviorConfiguration="AjaxBehavior" binding="webHttpBinding" bindingConfiguration="AjaxSecureBinding" contract="ShoppingCartService" />
      </service>  
    </services>
