DotNet4Neo4j/Neo4jClient: .NET client binding for Neo4j

A .NET client for Neo4j. Supports Cypher queries via fluent interfaces, and some indexing operations.

Grab the latest drop straight from the Neo4jClient package on NuGet.

Read our wiki docs - Currently OUT OF DATE

The official Neo4jClient build and nuget package is automated via AppVeyor.

Version 4.0.0 of Neo4jClient is now the stable version. There have been a lot of changes, additions, removals, so it's likely there will be breaking changes.

This isn't an exhaustive list of things you need to do, but I'll try to add things if I've forgotten them.

You will need to use the correct URI for the server version you are connecting to:

• 3.x server: http://localhost:7474/db/data
• 4.x server: http://localhost:7474/

• 3.x or 4.x server: neo4j://localhost:7687
• Worth reviewing the Neo4j Documentation to see what you need to use.

As this release is 100% async you will need to update any calls to Results or ExecuteWithoutResults to their Async equivalents.

• Async endpoints only
  • To get this release out, Neo4jClient is Async only now.
• Transactions will no longer use the TransactionScope class which means that MSDTC will no longer work.
  • This has been an issue since the dawn of Core/NetStandard - TransactionScope may be in NetStandard now - but the other classes the Transaction code was relying on wasn't.
• The GraphClient and BoltGraphClient will no longer support Neo4j 3.4 or lower.
  • Largely this is because the Neo4j.Driver that does the Bolt side of things only targets 3.5+, and keeping all the backwards compatibility means a lot of work, for little gain.

• Json.NET - 10.0.3 -> 12.0.3
• Neo4j.Driver.Signed - 1.7.2 -> 4.1.1

If you're changing from 2.x to 3.x, you'll want the below information, but you should really be on 4.x unless you have to target an older DB instance.

• Bolt!
• Transactions now use AsyncLocal<> instead of ThreadStatic
  • Transactions still don't work in the .NET Core version for the same reason as listed below (in Breaking Changes in 2.0)
  • TransactionScope does exist in NetStandard 2.0 - but some of the other bits surrounding the Transaction management doesn't.
• JSON.NET updated to 10.0.3
• PathResults doesn't work with Bolt, you need to use PathResultsBolt instead.

• JSON.NET updated to 9.0.1

• If using the DotNet Core version of Neo4jClient - transactions will not work. This will be returned when DotNet Core gets the TransactionScope (See this comment for more details).

I will not be updating the 3.x version of the client, the focus is on 4.x and the features that gives us. Neo4j no longer actively support Neo4j 3.4 so you should consider updating if you can. Largely - anyone using the 3.x version of the client is coping with it's deficiencies, and as 4.x addresses most of them. ¯_(ツ)_/¯
