Answer 1

I was recently getting errors like this from a web service when I had not configured it correctly to handle enough data eg: maxBufferPoolSize, maxReceivedMessageSize and the like.

In the httpbinding section of the client side app.config and server web.config.

Also if you are sending a large array the service behaviour and endpoint behavior sections of these files may need:

<dataContractSerializer maxItemsInObjectGraph="array size here"/>
