This post is going to use one of the tools provided by NSwag to generate C# client classes to provide access to an API. While the NSwag tooling provides multiple ways to discover the definition of an API we will be using the tooling to generate C# classes from an OpenAPI/Swagger specification.

Swagger tooling for API's built with ASP.NET Core. Generate beautiful API documentation, including a UI to explore and test operations, directly from your routes, controllers and models.
