Owin model and Kestrell request handling

• OWIN – Open Web Interface for .NET
• allows web apps to be decoupled from web servers
• defines standard way for middleware to be used in a pipeline to handle requests and provide responses
• ASP.NET Core applications can interoperate with OWIN-based applications, servers and middleware

Microsoft.AspNetCore.Owin package provides two adapter implementations:

• ASP.NET Core to OWIN
• OWIN to ASP.NET Core

This allows ASP.NET Core to be hosted on top of an OWIN compatible server/host or for other OWIN compatible components to be run on top of ASP.NET Core.
