Streaming Message Transfer:
Unidirectional or bidirectional streaming is enabled through the TransferMode property of the transport binding element.
Note that there are some restrictions on the use of streaming, especially when using certain WCF features, such as reliable messaging, transactions, and SOAP security, which may require buffering.
WCF supports two main types of quota: timeouts to guard against denial of service attacks and allocation limits to guard against excessive memory use.
