ASP.NET Core Anatomy

In ASP.NET Core everything starts with Program.cs, Main Method. ASP.NET Core apps require a startup class which serves as an alternative to Global.asax in ASP.NET 4.x. It uses a cross-platform Kestrel web server to serve the request and response. Here, IIS/Apache Tomcat/Nginx work as a delegation web server, and used to delegate the incoming request to the internal Kestrel web server.
