Receive an Exact Number of Bytes into a BinData

Demonstrates Socket.ReceiveBdN, which receives exactly the requested number of bytes and appends them to a BinData, continuing until the full count is satisfied.

Background. Inactivity is controlled by MaxReadIdleMs: the call fails if incoming bytes halt for longer than MaxReadIdleMs milliseconds before the full amount is received. A single receive returns only what is currently available, whereas this counted receive waits for an exact number of bytes.
