Today we are releasing version 2.1.4 of the Couchbase .NET SDK. This release focuses on bug fixes and other improvements; however, 2.2.0 which will be released early this fall will provide full support for Multi-Dimensional Scaling (MDS) and N1QL support along with “enhanced” durability and other features.


This release offers beta support for N1QL and partially supports MDS; in order to use N1QL and MDS together a single Couchbase Server 4.0 Beta (or soon RC) instance with the following services configured: Data, Indexing and Query. Cluster support for MDS is not yet available with this SDK release, however it will be in 2.2.0.

What is in this release?

2.1.4 includes the following Jira tickets:


  • [NCBC-925] – .NET Client 2.1.1 leaks connections when bucket does not exist
  • [NCBC-934] – GetFromReplica returns null when no replicas exist in the replica list
  • [NCBC-940] – Client receives “Cluster does not support Data Services” when Cannot Resolve Node Name
