Are there any c# Protocol buffers tcp messaging libs out there?

Basically i want to pub/sub Protocol buffer messages over a tcp async socket.

Are t开发者_StackOverflow社区here any open-source libs that pub/sub Protocol buffer messages over tcp?

thanks

At a push - how about a redis node? Ultimately though any pub/sub implementation would suffice as long as it handles binary. I happen to like redis as it solves a host of problems in one tool; BookSleeve is a fully async binary-safe redis client that works well with BLOBs such as protobuf fragments.

Disclosure: since I wrote both protobuf-net and BookSleeve I might be biased...
