Overview of this book

The ASP.NET Core 2.0 Framework has been designed to meet all the needs of today’s web developers. It provides better control, support for test-driven development, and cleaner code. Moreover, it’s lightweight and allows you to run apps on Windows, OSX and Linux, making it the most popular web framework with modern day developers. This book takes a unique approach to web development, using real-world examples to guide you through problems with ASP.NET Core 2.0 web applications. It covers Visual Studio 2017- and ASP.NET Core 2.0-specifc changes and provides general MVC development recipes. It explores setting up .NET Core, Visual Studio 2017, Node.js modules, and NuGet. Next, it shows you how to work with Inversion of Control data pattern and caching. We explore everyday ASP.NET Core MVC 2.0 patterns and go beyond it into troubleshooting. Finally, we lead you through migrating, hosting, and deploying your code. By the end of the book, you’ll not only have explored every aspect of ASP.NET Core MVC 2.0, you’ll also have a reference you can keep coming back to whenever you need to get the job done.

Understanding OWIN, Katana, and the new ASP.NET Core HTTP pipeline


In this recipe, we will get an in-depth look at OWIN, Katana, and the middleware pipeline in ASP.NET Core.

OWIN - an abstraction for decoupling

Open Web Interface for .NET (OWIN) is a standard that defines an interface between web servers and .NET web applications. Implementing OWIN allows us to create an abstraction between web apps, hosts, and servers, and to decouple .NET web applications from IIS. For example, to change the host in WebAPI to be self-hosted in a console application or a Windows service, change ASP.NET MVC or WebAPI with NancyFx.

The host is the process in our OS that loads the server and creates the pipeline. The server listens for the request on specific ports, redirects it to the pipeline, and returns the response to this request generated by the application. The application threads the received request and generates the response.

Katana - the Microsoft OWIN implementation
