WCF 400 Bad Request for Large Data

Question

Hi ,

I am developing a REST service in .NET 4.0 and here is my web.config file I an new to .NET and have been struggling for two days to understand why I am not able to upload data more than ~60KB.

I understood by googling that that the BufferSize has to be increased and tried modifing web.config file in different ways which never worked. Can someone help me.

Regards Hitesh

Answer 1

I think the only configuration changes of system.serviceModel required for increasing message size in REST scenario using ASP.NET compatibility are:

<system.serviceModel>
  <bindings>
    <!-- default binding configration used for all REST services -->
    <webHttpBinding>
      <!-- max allowed message size incresed to 500 000 Bytes -->
      <binding maxBufferSize="500000" maxReceivedMessageSize="500000" />
    </webHttpBinding>
  </bindings>
  <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
</system.serviceModel>

I got solution by adding maxBufferSize headers to tag. It works fine now
