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

Can I use StackExchange.Redis to store a Null value in Redis?

Is there any way to use the StackExchange.Redis client to store a Null value in Redis? If you use IDatabase.StringGet(key) then the returning of Null is used to signify that there "was no result". Therefore if you use IDatabase.StringSet(key, null)…

Does Stackexchange.Redis' fire and forget guarantees delivery?

I understand that CommandFlags.FireAndForget is intended for situations that you don't care about the response. Does it also guarantee delivery even though the response isn't important for the running application?
