Couchbase has released version 2.0.2 of its .NET SDK, which includes several updates and enhancements to support N1QL DP4, a new REST API that incorporates features like prepared statements, named and positional parameters, and configurable timeouts. The release also updates the Common.Logging dependency to version 3.0, removing reliance on deprecated NuGet packages. Enhancements to the ClusterHelper and IBucket interfaces facilitate better management of bucket references in multithreaded environments by introducing methods such as IsOpen, GetBucket, and RemoveBucket. The ViewRow.Key property has been modified to a dynamic Type to better reflect JSON structures. The update aims to improve the overall usability and performance of the SDK, especially in environments like ASP.NET applications, while also fixing various bugs identified in previous versions.
