When you have a large amount of data to transfer, the streaming transfer mode in WCF is a feasible alternative to the default behavior of buffering and processing messages in memory in their entirety.
In WCF any receiving message is delivered only once the entire message has been received. What I mean here is that first message is buffered at the receiving side and once it is fully received it gets delivered to the receiving end. The main problem with this approach is that the receiver end is unresponsive while the message is getting buffered. So default way of message handling in WCF is ok for small size messages but for the large size messages, this approach is not good. So to overcome this problem Streaming in WCF come into action.
