Hello there,

I have now investigated the 400 - BadRequest code for the last two hours. A lot of sugestions goes towards ensuring the bindingConfiguration attribute is set correctly, and in my case, it is.

Now, I need YOUR help before destroying the building i am in :-)

I run a WCF RestFull service (very lightweight, using this resource for inspiration: http://msdn.microsoft.com/en-us/magazine/dd315413.aspx) which (for now) accepts an XmlElement (POX) provided through the POST verb.

I am currently ONLY using Fiddler's request builder before implementing a true client (as this is mixed environments).

When I do this for XML smaller than 65K, it works fine - larger, it throws this exception: The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

Here is my web.config file (which I even included the client-tag for (desperate times!)):

<system.web>
    <httpRuntime maxRequestLength="1500000" executionTimeout="180"/>
  </system.web>
  <system.serviceModel>
    <diagnostics>
      <messageLogging logEntireMessage="true" logMalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" />
    </diagnostics>
    <bindings>
      <webHttpBinding>
        <binding name="WebHttpBinding" maxReceivedMessageSize="1500000" maxBufferPoolSize="1500000" maxBufferSize="1500000" closeTimeout="00:03:00" openTimeout="00:03:00" receiveTimeout="00:10:00" sendTimeout="00:03:00">
          <readerQuotas maxStringContentLength="1500000" maxArrayLength="1500000" maxBytesPerRead="1500000" />
          <security mode="None"/>
        </binding>
      </webHttpBinding>
    </bindings>
    <client>
      <endpoint address="" binding="webHttpBinding" bindingConfiguration="WebHttpBinding" contract="Commerce.ICatalogue"/>
    </client>
    <services>
      <service behaviorConfiguration="ServiceBehavior" name="Catalogue">
        <endpoint address="" 
                  behaviorConfiguration="RestFull" 
                  binding="webHttpBinding"
                  bindingConfiguration="WebHttpBinding" 
                  contract="Commerce.ICatalogue" />
        <!-- endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" / -->
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="RestFull">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehavior">
          <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true"/>
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

Thanks in advance for any help leading to succesfull call with >65K XML ;-)
