Hi,
There was similar thread three years ago here, however maybe something has changed since then.
We have quite few (80) custom APIs developed in D365 FO. Customer requested documentation in
Swagger. Generating yaml/json from pure c# web application is fairly easy with Swashbuckle package,
however in D365 it's a different story. Maybe already there is some tool/method to generate at least
some part of that file automatically based on data contracts?
