I've noticed there are a few solutions to allow the use of memcached on C# / ASP.NET:
memcacheddotnet
enyim.com Memcached Client
BeIT
Which one should I use? It seems like the enyim port has more active development, but I wanted to see what you guys recommend.
I use BeIT and i am happy with it.
Take a look at Velocity. Its Microsofts new alternative, its not stable yet but looks promising.
