While generating the c# client for an api an exception occurs. I isolated the smallest section of the API that fails and it can bee seen in the attached "sample-api.txt" file (json) The issue appears related to having an example node under the content type section (application/json) without having an schema node. That particular scenario is not flagged as an error is Swagger and the documentation does not point to schema being a mandatory node. sample-api.txt
