In this session we'll take a look into the transformation interfaces that ship as part of the Microsoft.AspNetCore.OpenApi NuGet package in ASP.NET Core 9 to see how we can build on top of them to enrich an OpenAPI document.

Using document, operation and schema transformers, we'll take a look at an approach to add rich examples and descriptions to an API to help make it even easier for other developers to create an integration that depends on our application's API.
