I'm using Couchbase 2.0 Beta with the latest .Net SDK and logging.
I'm just trying to save anything to the server. I've tried many things, but the result is always false.

----------------------------------------------------------------------------------
Dim result = CacheClient.Store(StoreMode.Set, key, dataString) // is always false!
----------------------------------------------------------------------------------

I've tried many things and after investigating the logs I found this error that keeps popping up.

=================================================================================================
2012-11-06 12:02:29,812 [22] ERROR Couchbase.CouchbasePool [(null)] <(null)> - Failed to initialize the pool. System.ArgumentException: bucket count must be a power of 2! at Enyim.Caching.Memcached.VBucketNodeLocator..ctor(String hashAlgorithm, VBucket[] buckets) at Couchbase.CouchbasePool.InitVBucket(ClusterConfig config, ISaslAuthenticationProvider auth) at Couchbase.CouchbasePool.ReconfigurePool(ClusterConfig config)
=================================================================================================

What should I do to resolve this? 1.8 was so simple to get things into the cache. I feel like this has been a headache to get working out of the box.

Below is my app.config.

Turns out this is a Windows 8 issue and I had to replace a .dll to make things work.

See this issue for the fix:
