WCF maxReceivedMessageSize not being read from config

Question

I have a the following server side app.config for a WCF service:

Answer 1

If you're still getting this error message while using the WCF Test Client, it's because the client has a separate MaxBufferSize setting.

To correct the issue:

1. Right-Click on the Config File node at the bottom of the tree
2. Select Edit with SvcConfigEditor

A list of editable settings will appear, including MaxBufferSize.

Note: Auto-generated proxy clients also set MaxBufferSize to 65536 by default.

Answer 2

There's more settings :-) Try "maxBufferPoolSize" and "maxBufferSize" on the <binding> tag.

But the biggest problem is: your endpoint does not reference that binding configuration!

<endpoint address="" 
          binding="wsHttpBinding" contract="Core.TOAService.ITOAService">

You need to add a reference to it so that it gets useful - just calling it "default" doesn't work.....

<endpoint address="" 
          binding="wsHttpBinding" 
          bindingConfiguration="default"
          contract="Core.TOAService.ITOAService">

You're ahead of your times ;-) In WCF 4 (with .NET 4.0 - sometime later this year 2009), you'll be able to define "default binding configurations" without having to explicitly name and reference them - but for now, you need to create a link between your endpoint and its binding and any binding (or behavior) configuration you have!

There are several places that you need to set the size. In your case I think that you need to add read quotas. Here is an example:

  <basicHttpBinding>
    <binding name="httpBasicBinding_Service" closeTimeout="00:03:00"
      openTimeout="00:03:00" receiveTimeout="00:10:00" sendTimeout="00:03:00"
      maxBufferSize="2000001"
      maxBufferPoolSize="2000001" maxReceivedMessageSize="2000001">
      <readerQuotas maxDepth="2000001" maxStringContentLength="2000001"
        maxArrayLength="2000001" maxBytesPerRead="2000001" maxNameTableCharCount="2000001" />
    </binding>
  </basicHttpBinding>
