Swagger-codegen generates enumerations whose first value is 1 instead of 0

I am facing an issue with swagge-codegen as I try to generate a c# client SDK regarding the generation of the models for enumerations. Indeed, I have some enumeration definitions in my Open API description, and the model generated from their description has a default value of 1, which is tricky for me because in my web API their default values are 0.

I haven't found the information on how to make the generated enum integer values start from 0, or not be explicitely set (and there for implicitely start from 0).

Swagger-codegen version

2.3.0-SNAPSHOT

Swagger declaration file content or url

Here is a sample of one of my enumeration definitions

"errorCode": {
"enum": [
"OK",
"Error"
],
"type": "string":

Use the sample OpenAPI enum with string values OK and Error to reproduce the generated C# model and inspect the C# generation templates or entry points responsible for enum values. Done means the generated enum uses zero-based or implicit integer values consistent with the reported API behavior.
