Question

I have a WCF Service operation which takes an object as a parameter. This object has a byte[] property among others. A Client program calls this service operation using a svcutil generated proxy.

when client program populates the object’s bype[] propery with size more than 50Kb it throws following error. (while an image size smaller than 50kb assigned to the byte[], it works).

The error which I am getting is:

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

This is my Server side Config:

<system.serviceModel>

   <messageLogging logMalformedMessages="false" logMessagesAtServiceLevel="false"
    logMessagesAtTransportLevel="false" />
</diagnostics>
<services>

Ok, I am answering my own question here –

Just found out that there is a setting on in server side config “maxReceivedMessageSize”. Once you set this to the max size you want server to accept, you are ready to go.

Thanks & Regards,
