WebSockets.Resilience

Targets net462 and net5.0. Full documentation is at https://scottoffen.github.io/websockets.

Overview

ResilientWebSocketClient layers reconnection, a configurable backoff strategy, a send queue that survives reconnect gaps, and fragmented-message reassembly on top of IWebSocketClient

A live WebSocket (from ClientWebSocket or WebSockets' own WebSocketClient) is a single, one-shot connection by design, it can't reconnect itself. ResilientWebSocketClient can't just hand one back the way WebSocketClient.ConnectAsync does; it owns the reconnect loop itself and gives the caller a stable send/receive surface across however many underlying connections happen along the way.

Using this package guarantees

Using this package means:

  • A dropped connection is detected and reconnected automatically, with the backoff strategy you choose.
  • A message sent while genuinely disconnected is queued and delivered once reconnected. This is a real guarantee: SendAsync never throws just because there's no live connection at the moment.
  • A message that fails to send is requeued rather than silently dropped, so a connection dying mid-send doesn't lose it.
  • Shutting down doesn't have to lose queued messages. DisposeAsync stays fast and abrupt, and can lose whatever's still queued; CloseAsync instead gives everything already queued a bounded chance to actually go out first.

What can't be guaranteed

A message sent in the exact instant a connection is dying, before either side has noticed yet. TCP doesn't guarantee a local send fails just because the remote end already reset the connection; a write can appear to succeed at the socket-buffer level into a connection that's already dead, with no exception raised.

Closing that gap completely needs an application-level acknowledgment protocol (the server confirms receipt, the client only clears its own queue on that confirmation), which requires server-side cooperation and is out of scope for a general-purpose client.

ResilientWebSocketClient requeues on a failed send, which narrows, but does not eliminate, the gap above.
