WCF Web Service Operation Throws Exception When Transferring More Than 50 Kbytes Bytes []

Question

I have a WCF Service operation that takes an object as a parameter. This object has the byte [] property among others. The client program invokes this operation using the proxy server generated by svcutil.

when the client program fills the bype [] object with a size of more than 50 KB, it throws the following error. (while the image size is less than 50 kbytes assigned to byte [], it works).

The error I am getting is:

Error System.ServiceModel.ProtocolException was unhandled Message = "The remote server returned an unexpected response: (400) Bad request."

This is my server side configuration:

    logMessagesAtTransportLevel="false" />
