Azure Logic Apps - Liquid Connector - version/flavor of liquid template engine?

Question

Does anyone know what flavor of liquid template engine Azure is using in the Liquid connector for logic apps? We were under the impression that it was DotLiquid but that doesn't appear to be the case.

Is there source code available for the liquid connector?

Answer 1

It is DotLiquid with Csharp naming convention.
