Silverlight & WCF: Max message size

Question

When I pass a list of objects out of my silverlight app using WCF everything works fine until the List grows too big. It seems that when I exceed 80 items I get the error: T

Answer 1

There are two config files. The silverlight clientconfig will let you send the larger message, but if you'r eusing WCF, there is a server web.config that limits the size of the received message (to prevent DDOS attacks).

Answer 2

In server side, change the config file to make the service can accept large message.

1. Add a basicHttpBinding configuration in <system.serviceModel> section:

   <?xml version="1.0" encoding="utf-8" ?>
   <configuration>
       <system.serviceModel>
          <bindings>
            <basicHttpBinding>
               <binding name="MyBasicHttpBinding" maxReceivedMessageSize="300000000">
                  <security mode="None"/>
                  <readerQuotas maxStringContentLength="300000000"/>
               </binding>
            </basicHttpBinding>
          </bindings>
   .......
   

2. Add the configuration to the service binding.

   <endpoint address="" binding="basicHttpBinding" bindingConfiguration="MyBasicHttpBinding" contract="WcfService1.IService1">
   

Answer 3

If you are sending out a large number of items from WCF, also make sure that maxItemsInObjectGraph is a relatively high number

<behaviors>
   <serviceBehaviors>
      <behavior name="YourBahvior">
         <dataContractSerializer maxItemsInObjectGraph="6553600"/>
      </behavior>
   </serviceBehaviors>
</behaviors>
