This article shows how to document your MVC 6 API using Swagger with Swashbuckle. Per default, it does not use your xml comments in the code and this needs to be configured if required.

SwaggerUI is more that just documentation - it actually allows developers to make authenticated calls to the API.

Swagger is a simple yet powerful representation of your RESTful API. Once integrated with WEB API, it becomes easy to test the API without using any third-party tool. In this post, we will see how to add Swagger to ASP.NET Core Web API.

Document your ASP.NET Core Web APIs with Swagger and auto-generate authenticated clients quickly and easily with Autorest.

For all intents and purposes HTTP and REST are just the implementation detail of the communication protocol. And unless the API you are exposing really maps well to resources which can be accessed as a tree like a filesystem or an object store like S3, treating REST like and end on itself just gets in the way and makes things more complicated than it should.

There are a few easy solutions that you can implement that will actually do all the documentation work for you. Microsoft has their own built-in version of this, however I'm going to focus today on a specification called "Swagger." More specifically, the implementation technology we'll be using to generate the Swagger documentation with the Web Api framework is called "Swashbuckle."

In a continuous delivery environment, we need to test each phase of our build and deployment pipeline as if they are layers that build on each other. Each of these layers can introduce additional integrations and abstractions on top of the previous layer.

In this column, rather than continue with Swashbuckle and the other Swagger tools, I'm going to look at part of the NSwag toolset. In part I'm doing this to illustrate one of the attractive aspects of the OpenAPI specification: The variety of tools that support it.

When delivering frequent updates to an API, versioning comes into play as soon as evolving an endpoint is not a feasible option anymore. So an API team has to have a process around versioning. One that is preferably less painful and more automated.

Versioning of your endpoints is important especially if you have 3rd party dependent clients of your REST API service. Any change in your endpoint, for example in data structure may impact clients even if it is backward compatible, clients may process your endpoint data in different ways, so even adding one additional property to your model may also impact functionality of the client which is consuming your endpoint.
