Setting Max Message and buffer size for WCF webhttp

There's a multitude of settings that might have an influence depending on your settings - try this:

<bindings>
  <webHttpBinding>
    <binding name="LargeWeb"
             maxBufferPoolSize="1500000"
             maxReceivedMessageSize="1500000"
             maxBufferSize="1500000">
      <readerQuotas 
            maxArrayLength="656000"
            maxBytesPerRead="656000"
            maxDepth="32"
            maxNameTableCharCount="656000"
            maxStringContentLength="656000"
            />
    </binding>
  </webHttpBinding>
</bindings>

By defining your "version" of the webHttpBinding and setting all those parameters to higher values, you should be able to get through any message size (almost).

Mind you: this does open up your system to the potential of being flooded with huge messages and thus be brought down to its knees (classic denial-of-service attacks) - that's the reason these limits are set fairly low - by design and on purpose.

You can change them to higher values - just be aware what you're doing and what the security risks are, if you do!

PS: In order to make use of these settings, you of course have to reference that binding configuration in your server and client side configs:

<client>
  <endpoint address="http://localhost"
            binding="webHttpBinding" bindingConfiguration="LargeWeb"
            contract="IMyService" />
</client>
<services>
  <service>
    <endpoint address="http://localhost"
              binding="webHttpBinding" bindingConfiguration="LargeWeb"
              contract="IMyService" />
  </service>
</services>
