A high performance .NET redis client library

StackExchange.Redis is a high-performance redis client library for .NET and Mono applications, allowing massively concurrent usage from multiple threads (for example, on a busy web site). The library exposes synchronous, asynchronous and fire-and-forget APIs, allowing it to support a wide variety of use-cases. Additionally, the client supports internal management of connections to multiple servers, including both master/slave setups and redis "cluster". The entire set of redis functionality is included (including auto-resubscribe for pub/sub connections), with the exception of the blocking pop operations, which are not compatible with the multiplexer design.

The client was designed, created and released by the Stack Exchange development team, and is the redis client that drives the Stack Exchange Network (including Stack Overflow). It supersedes the BookSleeve client that Stack Exchange had been using previously

Why does StackExchange.Redis frequently throw an "Unexpected response to EXEC: MultiBulk: 0" exception during transaction.ExecuteAsync()?

I tried debugging through the code and it seems to repro mainly when multiple clients are trying to modify the same key in a transaction. Retrying the transaction usually gets rid of the error, but is there any reason why the exception is thrown in…
