please consider targeting .net standard, given the GA of Azure Cosmos DB this allow using the library of a number of hardware/software platforms

Add support for sessions that allow a transaction to span over multiple requests.

Gremlin.Net currently only targets .NET Standard 1.3 which is supported by .NET Framework 4.6 and higher. Since many users still use .NET Framework 4.5, it would be a good idea to also target that framework to make Gremlin.Net accessible to those users.

The reason why Gremlin.Net currently doesn't target anything below .NET Standard 1.3 was that some of its dependencies like System.Net.WebSockets only target that version (and the respective .NET Framework 4.6). But since these dependencies where already part of .NET Framework 4.5, it should be possible to add that as a target framework and not use these NuGet packages for that target.

Hi

I have recently moved to Gremlin.net 3.3.4

I am using the concept

        string gremlinDatabasePath = $"/dbs/{databaseName}/colls/{collectionName}";

        var _server = new GremlinServer(gremlinEndPoint,
                                        port,
                                        enableSsl,
                                        gremlinDatabasePath,
                                        gremlinAuthKey);


      where the gremlinEndPoint is taken from the azure portal and the https:// has been removed

        var client = new GremlinClient(_server,
                                       new GraphSON2Reader(),
                                       new GraphSON2Writer(),
                                       GremlinClient.GraphSON2MimeType);

what causes this exception thatcomes up. I left the Azure.Document.Graph preview API so I have to get it to worlk

Some endpoints are secured using username password connections.

At this moment this is not yet supported by Gremlin.Net.

Hi,

Since I updated to the 3.3.1 and 3.3.2 of the Nuget package, there is a Null Reference Exception.

Here is the stack trace :

   at Gremlin.Net.Driver.Connection.<ReceiveAsync>d__14`1.MoveNext()

   at PartitionedGraph.Program.<ExecuteGremlinServerQueryAsync>d__3.MoveNext()

And the code sample:

string query = "g.V().drop()";

GremlinServer server = new GremlinServer(gremlinServerEndPoint, serverPort, true, $"/dbs/{databaseId}/colls/{collectionId}", primaryKey);
                
using (GremlinClient client = new GremlinClient(server))
{
    IEnumerable<dynamic> results = await GremlinClientExtensions.SubmitAsync<dynamic>(client, requestScript: query);

    foreach (dynamic result in results)
    {
        Console.WriteLine(result.ToString());
    }
}

I know this is not the right version project, but I can not find the original repository for the Nuget package.

This is not blocking, since I can use the 3.2.8 version of the NuGet pacakge.

Thanks in advance.

Hi,

i saved a time in String UTC Format in the Cosmos GraphDB.
As "yyyy-MM-ddTHH:mm:ssZ"

As i retrieved it, i though i would come back as string but it comes back as DateTime.

Is think this comes from the NewtonJsoft SerializerSettings in the Gremlin.net

Is there any way to change this default Settings to my behavior?

I want to do something like this:

	    JsonConvert.DefaultSettings = () => new JsonSerializerSettings
	    {
	        DateParseHandling = DateParseHandling.None,
	        DateFormatString = "yyyy-MM-ddTHH:mm:ssZ"
	    };

Thanks!

Hello! The latest nuget package 0.2.1 doesn't seem to be strong-name signed.

CSC : error CS1577: Assembly generation failed -- Referenced assembly 'Gremlin.Net' does not have a strong name

Is this an oversight?

Since many graph databases like Titan and DSE Graph consist of more than just one server, Gremlin.Net should be able to send requests to multiple servers.

Round-robin should be used as the default scheduling algorithm for requests.

Add support for PLAIN SASL authentication described in: http://tinkerpop.apache.org/docs/current/dev/provider/#_authentication

RequestMessage.RequestId returns Guid.NewGuid(); this causes a different ID to be generated any time you call the property getter. For example, I was trying to log request and response IDs, but the value was different every time I inspected it.

I think the value should be assigned during construction, and that value returned, so that it's the same throughout the lifetime of the request. For example:

private readonly Guid _requestId = Guid.NewGuid();

[JsonProperty(PropertyName = "requestId")]
public Guid RequestId => _requestId;

Also, I'm unable to find a reference on this, but I have seen in other implementations that the authentication message uses the same request ID as the original request. This makes sense to me, as it is part of the same logical request.

When call just CloseAsync it is possible to get exception (Remote side closed the WebSocket connection without complete closing confirmation: WebSocketErrorCode-ConnectionClosedPrematurely-System.Net.WebSockets.WebSocketError):

I think, calling CloseOutputAsync should change this situation.

I have happened across this repo when I was looking for a good .NET package to query gremlin queries with, and I thought that this is the state of art in .NET - but today a coworker opened my eyes to the official implementation, so I wonder if the readme can be updated to point people over to that: https://github.com/apache/tinkerpop/tree/master/gremlin-dotnet

Thanks a lot!
