C# (Newtonsoft): integer enums serialize as strings instead of numbers

[jabdinghoff]

Problem

The C# Newtonsoft renderer generates converters that serialize integer enum values as strings instead of numbers.

Given a schema with:

{ "decimation": { "type": "number", "enum": [0, 1, 3, 7, 15] } }

The generated converter does:

// ReadJson
var value = serializer.Deserialize<string>(reader);
switch (value)
{
    case "0": return Decimation.The0;
    ...
}

// WriteJson
case Decimation.The0:
    serializer.Serialize(writer, "0"); // writes "0" (string) instead of 0 (number)

Root Cause

The enum serialization goes through the transformation pipeline (emitDecodeTransformer/emitTransformer in NewtonSoftCSharpRenderer.ts) which hardcodes Deserialize<string>. This is deeply integrated and needs a larger refactor to support typed enum values.

Expected Behavior

Integer enums should serialize as JSON numbers (7) not strings ("7").
