BufferManager Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

When implemented in a derived class, 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 and uses fewer resources than creating and destroying a buffer every time you need to use one.
