Transfer large of data using wcf service

When I try to transfer a large data in WCF, I get this error:

The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:requete. The InnerException message was 'There was an error deserializing the object of type System.String. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 1, position 8843.'. Please see InnerException for more details.

This is my app.config file :

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.web>
    <compilation debug="true" />
  </system.web>
  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="NewBinding0" maxBufferSize="52428800" maxBufferPoolSize="52428800">
          <readerQuotas maxStringContentLength="52428800" />
        </binding>
      </basicHttpBinding>
    </bindings>
    <services>
      <service name="TSO_WCF.Service1">
        <host>
           <baseAddresses>
               <add baseAddress="http://localhost:8732/Design_Time_Addresses/TSO_WCF/Service1/" />
           </baseAddresses>
        </host>
        <!-- Service Endpoints -->
        <!-- Unless fully qualified, address is relative to base address supplied above -->
        <endpoint address="" binding="wsHttpBinding" contract="TSO_WCF.IService1" >
           <identity>
              <dns value="localhost"/>
           </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
       <serviceBehaviors>
          <behavior>
             <serviceMetadata httpGetEnabled="True"/>
             <serviceDebug includeExceptionDetailInFaults="False" />
          </behavior>
       </serviceBehaviors>
    </behaviors>
</system.serviceModel>
<appSettings>
   <add key="Mapping" value="D:\workspace\oddo.app.ldw.tsomanagertool\ProjetTSO\MappingsXML"/>
</appSettings>
</configuration>

You should increse the MaxStringContentLength on the server and client binding. At this moment you are using the default value of 8192.

Perhaps you could change your binding /use streaming. See this page: http://msdn.microsoft.com/en-us/library/ms733742.aspx
