IResultCursor.Current.Values changed output format

[mdfrenchman]

Describe the bug Not sure this is a bug, but might be more an undocumented change.

The output of IResultCursor.Current.Values changed format when serialized to a string with .NET Driver Version 5.17.0 and prior (not sure of 5.18.1, didn't test it) format was: {'someKey':'someValue'}

with .NET Driver Version 5.20.0 format is: {'Key':'someKey', 'Value', 'someValue'}

To Reproduce

var resultCursor = await tx.RunAsync(query, params);
while (await resultCursor.FetchAsync()) 
{
  sb.AppendLine(jsonSerializer.Serialize(resultCursor.Current.Values));
}

Expected behavior I'd expect to see the change documented or mentioned.

Version Info (please complete the following information):

• .NET Version: .NET Framework 4.8.1
• .NET Driver Version: 5.20.0
• Neo4j Server Version & Edition: Enterprise 5.19.0

Additional context The Summary.Counters ICounter object still behaves the same way it used to. It also uses the same serialization method.

Hi there. Thanks very much for finding this! I'm investigating right now. I wonder if you could tell me how the jsonSerializer variable in your sample code is created, so that I can reproduce your situation exactly? Thanks!

Hey @RichardIrons-neo4j ,

var jsonSerializer = new JavaScriptSerializer();

Oddly, that class is coming from using System.Web.Script.Serialization;

It's an old code base (hence Framework), so not entirely sure why it's using that serializer.

I was able to test using System.Text.Json and that worked correctly as it's supposed to.

Chalk this up to an old System.Web Serializer and how it handles Dictionaries, I guess.
