我想从我的Silverlight 3应用程序调用WCF服务。 但是...当试图在我的web项目中创建'启用silverlight的wcf服务'时,我的VS2008在创建项目时(我认为在编辑web.config时)崩溃。'正常'SVC与'Silverlight'SVC(WCF)

所以我想:让我们创建一个'普通'wcf服务,并手动将其编辑为'启用silverlight的web服务'。

所以我想知道有什么区别,第二:为什么从Silverlight应用程序调用的服务和非Silverlight应用程序之间存在差异?

这是我现在有一个绑定(无我有一个接口协议的业务,恰恰暴露了直接的班,开始):

<system.serviceModel> 
     <behaviors> 
      <serviceBehaviors> 
       <behavior name="RadControlsSilverlightApp1.Web.GetNewDataBehavior"> 
        <serviceMetadata httpGetEnabled="true" /> 
        <serviceDebug includeExceptionDetailInFaults="false" /> 
       </behavior> 
      </serviceBehaviors> 
     </behaviors> 
     <bindings> 
      <customBinding> 
       <binding name="customBinding0"> 
        <binaryMessageEncoding /> 
        <httpTransport /> 
       </binding> 
      </customBinding> 
     </bindings> 
     <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> 
     <services> 
      <service behaviorConfiguration="RadControlsSilverlightApp1.Web.GetNewDataBehavior" 
      name="RadControlsSilverlightApp1.Web.GetNewData"> 
       <endpoint address="" binding="customBinding" bindingConfiguration="customBinding0" 
       contract="RadControlsSilverlightApp1.Web.GetNewData" /> 
       <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
      </service> 
     </services> 

    </system.serviceModel> 

这一个不能正常工作,因为当我从Silverlight应用程序添加引用它,我得到的消息:

(PS,该服务可以在浏览器启动时,我得到这个:

svcutil.exe http://localhost:9599/GetNewData.svc?wsdl

主要是什么你做的是:

Web.config is configured to use basicHttpBinding since Silverlight does not support ws*. 
ASP compatibility mode: <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> 

因此,一个良好的开端将转换您的服务使用basicHttpBinding的。查看Configuring Services Using Configuration Files了解更多关于适用于服务的web.config部分。

可以有弹性一些损失于使用在Silverlight enabled WCF Service Template is Bad Practice
