BinaryMessageEncodingBindingElement

The binding element that specifies the .NET Binary Format for XML used to encode messages.

Binding

Contains the binding elements that specify the protocols, transports, and message encoders used for communication between clients and services.

BindingContext

Many Windows Communication Foundation (WCF) features require the use of buffers, which are expensive to create and destroy. You can use the BufferManager class to manage a buffer pool. The pool and its buffers are created when you instantiate this class and destroyed when the buffer pool is reclaimed by garbage collection. Every time you need to use a buffer, you take one from the pool, use it, and return it to the pool when done. This process is much faster than creating and destroying a buffer every time you need to use one.
