[BUG] ON/OFF Enum values generated as boolean for scharp

[RomanSoloweow]

I have 3.0.1 Open api Spec with enum which constains ON/OFF values

    PowerState:
      type: string
      enum:
      - ON
      - OFF

It's generated as True/False for scharp rest client

This not only affects C#, but also other generators like Java Spring. I followed the path where the enum values are coming from and ended up in Swagger's OpenAPI parser, i.e. it's not a problem of the OpenAPI generator itself, but from on of its dependencies. There is an issue for this swagger-api/swagger-parser#1205.

Workaround: Explicitly mark your enum values as strings. Example:

components:
  schemas:
    MyEnum:
      type: string
      enum:
        - "YES"
        - "NO"
        - "SOME_OTHER_VALUE"
