View Complete WCF response on error using Visual Studio 2010

Question

In Visual Studio 2010 I get an error which tells me the first 1024 bytes of a response from a WCF service when consumed, but no more.

I would really like to see the entire response so I can work out what is going wrong, where can I get this info from? Is there a way of logging the full text of an error or are they all limited by the 1024 byte rule?

How to View more than 1024 bytes of a wcf response when an error occurs in Visual Studio 2010?

Answer 1

If you are doing this in debugging mode, where you have the exact steps pre-identified - you could try if setting maxReceivedMessageSize to a large value helps.

As the description says on the docs:

maxReceivedMessageSize

A positive integer that specifies the maximum message size, in bytes, including headers, that can be received on a channel configured with this binding. The sender of a message exceeding this limit will receive a SOAP fault. The receiver drops the message and creates an entry of the event in the trace log. The default is 65536.

In your case, it might have been set to a lower value.

You could also check if the maxBufferPoolSize has been set correctly - it seems that only one buffer worth of 1024 bytes are being transmitted back, which is possible if someone set the pool size as 1 instead of default 512.
