silverlight-4.0 - 自定义 WCF RIA 服务终结点

Question

是否可以自定义 WCF RIA 服务端点的参数？具体来说，我想为端点创建一个自定义绑定(bind)并增加 maxReceivedMessageSize允许发送大小为几兆字节的文件的内容。

我尝试干预 web.config，但出现以下错误:

[InvalidOperationException]: The contract name MyNamespace.MyService could not be found in the list of contracts implemented by the service MyNamespace.MyService

网络配置

<system.serviceModel>
  <bindings>
    <customBinding>
      <binding name="CustomBinaryHttpBinding">
        <binaryMessageEncoding />
        <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />
      </binding>
    </customBinding>
  </bindings>
  <services>
    <service name="MyNamespace.MyService">
      <endpoint address="" binding="wsHttpBinding" contract="MyNamespace.MyService" />
      <endpoint address="/binary" binding="customBinding" bindingConfiguration="CustomBinaryHttpBinding" contract="MyNamespace.MyService" />
    </service>
  </services>
  <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>

我们有一个类似的问题 - 我们想使用 WCF-RIA 服务调用操作将大型位图从 Silverlight 客户端发送到服务器。

Web.config 中的以下更改对我们有用:

<httpRuntime requestValidationMode="2.0" maxRequestLength="6225920"/>
