Receive a Block of Bytes to a File

Demonstrates Socket.ReceiveBytesToFile, which receives one available block of bytes and appends it to a file.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

Background. Any buffered data is written first; otherwise a single receive operation is performed. The method appends, so repeated calls accumulate received blocks in the file.
