Creating Modern WebAPIs with ASP.NET Core

In distributed applications, the backend plays a decisive role, and the development of the backend has become a separate area. It should be quick and easy to use, provide the data for the frontend and be well documented. In this talk by Fabian Gosebrink you will not only hear how to create a RESTful Web API with ASP.NET Core. You'll also learn how to document it with tools and how to extend it with useful features. The end result is a clean backend that can be used from any client.
