I was able to make an Open Api 3 definition work with SwaggerUI through ServiceStack.OpenApi. I followed steps given in https://forums.servicestack.net/t/is-swagger-ui-support-to-the-latest-version-3-0-4/3751 (I took latest 3.1.0 version) and was able to generate the curl through the swagger-ui (seems not to work with 3.0.4).
Any plans on integrating Open Api 3 ?
Thanks in advance,
There's no immediate plans, you can submit a feature request on UserVoice so we can measure interest and prioritize support for new features.
