Features:
TcpSocketClientandTcpSocketListenernow supports setting of the buffer size used when sending data. If unset, this defaults to zero (unbuffered). This also addresses an inconsistency in default buffer sizes between .NET platforms and WinRT platforms. Thanks @xen2TcpSocketListenernow supports os-based/ephemeral port selection. When passing0to theportparameter ofStartListeningAsync, the selection of bound port is deferred to the operating system. You can determine what port was bound by checking theLocalPortproperty.
