Hi!

I know it definitely works with Aura, which is neo4j+s only - so can you show the code you are running, as I can't replicate this.

Oh, I'm trying to connect to Aura. This is what I attempted to run in my dotnet 6 project:

Startup.cs

public void ConfigureServices(IServiceCollection services)
{
        var client = new GraphClient(new Uri(Configuration["Uri"]),
                Configuration["Username"], Configuration["Password"]);

        client.ConnectAsync().Wait();        // Exception on this line

        services.AddSingleton<IGraphClient>(client);
}

Sure, so you can't use HTTP to connect to Aura, you need to use Bolt - which means you need to use the BoltGraphClient - so swap GraphClient for BoltGraphClient:

public void ConfigureServices(IServiceCollection services)
{
        var client = new BoltGraphClient(Configuration["Uri"],
                Configuration["Username"], Configuration["Password"]);

        client.ConnectAsync().Wait();        // Exception on this line

        services.AddSingleton<IGraphClient>(client);
}

Thanks! It worked.
