The Neo4jClient, a main .NET client for Neo4j, has been revived after its developer stepped away. The new version, 1.1.0.1, includes significant improvements such as transaction support, use within a TransactionScope, and authentication capabilities. The client is now being managed by Chris, who aims to keep it in sync with Cypher and integrate Bolt serializer. He also plans to add LINQ integration and better interaction with PowerShell and Windows world. Users are encouraged to provide feedback and collaborate on the project through GitHub or email/tweet.
