unable to load wcf restful help page after changing transferMode to "Streamed"

In my project, a wcf restful service, which allow users to upload photos to the web service.

After changing config settings to allow large file upload. (add binding configuration, i.e. "TransferMode", "BufferSize", etc.) All Operation contracts are all working as expected.

However, the service help page for the endpoint stopped working.

The help page comes back, once I remove the binding config setting on my endpoint

How can I fixed this?? where did i missed

thank you all

<bindings>
          <webHttpBinding>
              <!-- buffer: 64KB; max size: 64MB -->
              <binding name="StreamedBinding" closeTimeout="00:01:00" openTimeout="00:01:00" 
                       receiveTimeout="00:10:00" sendTimeout="00:01:00" transferMode="Streamed" 
                       maxBufferPoolSize="67108864" maxBufferSize="65536" maxReceivedMessageSize="67108864">
              </binding>
          </webHttpBinding>
</bindings>

<service name="WCFRestFul.ApiRestful">
        <endpoint address="" binding="webHttpBinding"
                  bindingConfiguration="StreamedBinding" bindingName="StreamedBinding" 
                  contract="WCFRestFul.IApiRestful" behaviorConfiguration="web" />
 </service>

Upd开发者_运维知识库ate: I think it is not just because of the transfer mode, but maybe some other setting as well. The service help page comes back once I remove the "bindingConfiguration" in the code above. I have 2 endpoints. The other endpoint don't have the "bindingConfiguration", and the service help page works fine on that. I definitely missed some thing here, maybe some thing simple. any help will be greatly appreciated

I took carlosfigueira advice, painfully removed my config setting one at a time.

I changed my config settings from

OLD Code

<bindings>
          <webHttpBinding>
              <!-- buffer: 64KB; max size: 64MB -->
              <binding name="StreamedBinding" closeTimeout="00:01:00" openTimeout="00:01:00" 
                       receiveTimeout="00:10:00" sendTimeout="00:01:00" transferMode="Streamed" 
                       maxBufferPoolSize="67108864" maxBufferSize="65536" maxReceivedMessageSize="67108864">
              </binding>
          </webHttpBinding>
</bindings>

To Final working version (transferMode="Streamed" is removed)

<bindings>
 <webHttpBinding>
<binding name="StreamedBinding" maxReceivedMessageSize="67108864" />
 </webHttpBinding>
</bindings>

finally the service help page is back.

However I can't understand why it is back same as why it was turned off.

anyway, this is the working solution for my case. hope someone would find it helpful.

What do you mean by saying that it stops working? In the example below the help page is still returned by the service (and I tried using both IE and Chrome, and they were able to see the page).
