3.0.1 - NET 4.5.2 Supported again

Version 3.0.0 didn't support .NET 4.5.2, Version 3.0.1 does!

3.0.0 - Bolt Release!

We finally add Bolt to the Client!

In theory there is only one code change you need to do (assuming you're passing around IGraphClient), from:

var client = new GraphClient(new Uri("http://localhost:7474/db/data"), "user", "pass");

to

var client = new BoltGraphClient(new Uri("bolt://localhost:7687"), "user", "pass");

Adds CustomHeaders to the Query

Allows a user to specify CustomHeaders to a query to enable you to further control the queries being sent.

client.Cypher.CustomHeaders(new NameValueCollection {{"key", "value"}})

Also includes the MaxExecutionTime property to allow a user to define the execution time on a per query basis (in milliseconds):

client.Cypher.MaxExecutionTime(1000)

Adds 'ThenBy' and 'ThenByDescending' Methods

Now you can do:

.OrderByDescending("x").ThenBy("y")

Which will generate:

ORDER BY x, y DESC

OrderByDescending works for multiple elements

Previously doing .OrderByDescending("x", "y") would generate ORDER BY x y DESC
Now it will generate ORDER BY x DESC y DESC

Makes NeoException Serializable

NeoException is now serializable.

Uses CustomJsonConverters first for Deserializtion

First raised in Issue #136 - Neo4jClient Serializes POCO classes using CustomJsonConverters first, before using default. Deserialization used default, then custom.

This meant you could serialize something, but not be able to deserialize it.

Now custom serializers are used first for deserialization, default then following.

Where clauses sometimes still did Cypher 1.9 Null when against a 2+ DB

Some of the flows in .Where were still suffixing properties with ?, which is Cypher 1.9. There was nothing in the generation to respect the capability detection.

Sends X-Stream header

Now for Neo4j instances > 1.8 the X-Stream header is attached.
