The remote server returned an unexpected response: (413) Request Entity Too Large.

Question

I'm trying to build a WCF Application service, using FW4.0. My service work correctly when transferring EntiryFramework object between Server and client. But I'm having problem passing EF object from Client to Server.

Here some more detail about my environment: - The service is running in debug mode locally on IIS - I'm running all this on my Windows 7 - I'm using Visual Studio 2010 on FW4.0

I'm trying to send a object (tblClient) to server to save the record, but a keep having the error (413) Request Entity Too Large. Here the full stack:

I've do some research and all point to the maxBufferSize and/or maxBufferPoolSize and/or maxReceivedMessageSize witch is not large enough in the Client config App.Config. So I inscresed them to maximum value : maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" But still the error remain.

Here my full Client App.Config

<?xml version="1.0" encoding="utf-8" ?> <configuration>   <system.diagnostics>     <sources>       <!-- This section defines the logging configuration for My.Application.Log -->       <source name="DefaultSource" switchName="DefaultSwitch">         <listeners>           <add name="FileLog"/>           <!-- Uncomment the below section to write to the Application Event Log -->           <!--<add name="EventLog"/>-->         </listeners>       </source>     </sources>     <switches>       <add name="DefaultSwitch" value="Information" />     </switches>     <sharedListeners>       <add name="FileLog"            type="Microsoft.VisualBasic.Logging.FileLogTraceListener, Microsoft.VisualBasic, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL"            initializeData="FileLogWriter"/>       <!-- Uncomment the below section and replace APPLICATION_NAME with the name of your application to write to the Application Event Log -->       <add name="EventLog" type="System.Diagnostics.EventLogTraceListener" initializeData="MVVM Sampling"/>     </sharedListeners>   </system.diagnostics>   <system.serviceModel>     <bindings>       <basicHttpBinding>         <binding name="BasicHttpBinding_IService" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"/>       </basicHttpBinding>     </bindings>     <client>       <endpoint address="http://localhost:7803/Service1.svc" binding="basicHttpBinding"           bindingConfiguration="BasicHttpBinding_IService" contract="ServiceReference1.IService"           name="BasicHttpBinding_IService" />     </client>   </system.serviceModel> </configuration> 

and the full Web.Config WCF service Web.Config

Answer 1

For the record

I think I got it. The Web.Config from the service does not have the binding information. I placed this info in it, and voila!

<bindings>       <basicHttpBinding>         <binding maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Text">           <readerQuotas maxDepth="2000000" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />         </binding>       </basicHttpBinding> </bindings> 

Note here that the binding did not have a name specified.

Answer 2

You don't have an explicit endpoint (meaning one defined in your config file) for your service, so the binding configuration you declared ("BasicHttpBinding_IService") isn't being used. WCF is providing a default endpoint along with a default binding (basicHttpBinding unless you overrode it in the protocolMapping section of the config file).

You have two ways to resolve this in your service's config file:

You can make the "BasicHttpBinding_IService" configuration the default by removing the name attribute:

<binding maxBufferPoolSize="2147483647"..... 

Or you define an endpoint explicitly in the config and assign your binding configuration to the bindingConfiguration attribute of the endpoint.

<services>     <endpoint address=""                binding="basicHttpBinding"               bindingConfiguration="BasicHttpBinding_IService"                    contract="ServiceReference1.IService"  /> </services>
