I am looking for cache server for .NET. What can you suggest? As i know memcached has provider for .net. Is it good enough to use for .net in production?
though there are numbers of third party caching solutions are available for .NET but if we narrow done the research based upon Google and word of mouth, it might be 1) Memcached 2) Appfabric 3) NCache
firs two are free/open source software so they have some limitations in it, while on the other hand NCache has a lot to offer as compared to others, but you have to buy it. but it has also a free version available called as NCache Express. below are two important links in this regard,

See the post Top caching libraries for .NET for several options, including both free and commercial. The choice will vary based on your actual need.
If you're willing to run your cache server in Linux, you could use Redis, and use the BookSleeve library from .NET, this is what StackOverflow uses

Scale Out State Server is an excellent solution. It's not free, but for large-scale applications, it's one of the best options that we found.
NCache is another option, though I have no experience with it.
For enterprise scale (and budget) there's Oracle's Coherence. It works extremely well, though it's extremely pricey.
Here's another SO question with some information that may or may not be helpful:
Caching Solutions
AppFabric is another popular solution from Microsoft.
Memached is plenty good for production, probably best using the enyim provider.
Couchbase provide a good web ui and easy memcached install on windows. Free if on a single server. It's great to be able to monitor your cache instance.
They have paid for solutions but and their own server.
AppFabric as mentioned is another obvious candidate but not a mature as memcached. AppFabric is an application server and can also provide distributed caching like membase
