RESTful WCF (4.5.2) service errors with "413 Entity Request Too Large"

Question

this seems to be a really common question - and I've read through a ton of comments here on SO and other sites. Problem is that even after fixing up my configuration I'm still getting the 413 error when sending an ~50K payload.

Here's the relevant portion of the service config...

<system.serviceModel>
<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
<services>
  <service name="Sync.Inbound" behaviorConfiguration="serviceWebConfiguration">
    <endpoint address="" binding="webHttpBinding" bindingName="defaultRest" behaviorConfiguration="web" contract="Sync.IInbound"  />
  </service>
</services>
<bindings>
  <webHttpBinding>
    <binding name="defaultRest" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" transferMode="Streamed">
      <readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="2147483647" maxNameTableCharCount="2147483647" />
      <security mode="None" />
    </binding>
  </webHttpBinding>
</bindings>
<behaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp  />
      <dataContractSerializer  maxItemsInObjectGraph="2147483647"  />
    </behavior>
    <behavior name="json">
      <enableWebScript />
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior name="serviceWebConfiguration">
      <serviceMetadata httpGetEnabled="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>

I'm testing by calling this from a simple C# console application via an httpWebRequest... Anybody see anything I'm missing in the service config?

You need to set the bindingConfiguration attribute to "defaultRest" on the service endpoint element, otherwise the service will not use the specified binding configuration block.

The sample above shows the binding configuration name in a "bindingName" attribute rather than the "bindingConfiguration" attribute. Therefore, you need to change:

<endpoint ... bindingName="defaultRest"

to:

<endpoint ... bindingConfiguration="defaultRest"

Example:

 <system.serviceModel>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
    <services>
      <service name="Sync.Inbound" behaviorConfiguration="serviceWebConfiguration">
        <endpoint address="" binding="webHttpBinding" bindingConfiguration="defaultRest" ...
      </service>
    </services>
    <bindings>
      <webHttpBinding>
        <binding name="defaultRest" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" transferMode="Streamed">
          <readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="2147483647" maxNameTableCharCount="2147483647" />
          <security mode="None" />
        </binding>
      </webHttpBinding>
    </bindings>

Thank you Seymour! Works perfectly! – James Colyer Nov 13 '15 at 13:37 — James Colyer, Nov 13 '15 at 13:37

You might want to change up maxItemsInObjectGraph for your services dataContractSerializer to allow larger collections through.

<serviceBehaviors>
  <behavior name="SecureServiceBehavior">
    <serviceMetadata httpGetEnabled="true" httpsGetEnabled="false"/>
    <serviceDebug includeExceptionDetailInFaults="true"/>
    <dataContractSerializer ignoreExtensionDataObject="true" maxItemsInObjectGraph="2147483647"/>
    <serviceTimeouts transactionTimeout="00:03:00"/>
    <serviceThrottling maxConcurrentCalls="10" maxConcurrentSessions="10" maxConcurrentInstances="10"/>
  </behavior>
</serviceBehaviors>
