swagger .net core API ambiguous HTTP Action debugging

Question

Implementing Swashbuckle/Swagger with .net Core 2 API I am now receiving the 500 error when accessing swagger.json:

NotSupportedException: Ambiguous HTTP

Answer 1

As i mentioned at "Swashbuckle not creating swagger.json file" :

1. Decorate all actions with explicit Http Methods like[HttpGet("xxx")],[HttpPost("xxx")] or ... instead of [Route("xxx")].
2. Decorate public methods in controllers with [NoAction] Attribute.
