Notes about aspnetcore generator updates:

supported environments

ASP.NET Core 2.0, 2.1, 2.2 (default)

significant options

--interface-only : only generate interfaces for controllers
--interface-controller : generate interfaces for controllers, implemented by a default controller implementation

when neither interface-only nor interface-controller are set, no interfaces are generated.

--aspnet-core-version (e.g. --aspnet-core-version 2.0)

Such options are usable:

• via CLI, e.g. --aspnet-core-version 2.0 or --additionalProperties aspnet-core-version=2.0
• via generator web service / programmatically as additionalProperties, e.g.:

{
  "lang": "aspnetcore",
  "specURL": "https://petstore3.swagger.io/api/v3/openapi.json",
  "type": "SERVER",
  "codegenVersion": "V3",
  "options": {
    "additionalProperties": {
      "aspnet-core-version": "2.0",
      "interface-only": true      
    }
  }
}   

• via generator web service / programmatically as additionalProperties, e.g.:adding them to codegenArguments member of Options, e.g:

{
  "lang": "aspnetcore",
  "specURL": "https://petstore3.swagger.io/api/v3/openapi.json",
  "type": "SERVER",
  "codegenVersion": "V3",
  "options": {
    "codegenArguments": {
      "aspnet-core-version": "2.0",
      "interface-only": true      
    }
