MVC 4.0, Part 08 of 11: Architecture

Course description

In this course we’ll explore some of these real-time communication options, including HTTP polling, HTTP long polling, server-sent events, and the news of the bunch, Web sockets. You’ll also learn about Microsoft’s response to this need with a variety of technologies, including the SignalR library. Next we’ll explore two pieces of the basic ASP.NET infrastructure that are useful in some situations when building applications. The first is HTTP handlers and the other is HTTP modules, each of which are implemented as .NET classes that implement specific interfaces. An HTTP handler executes whenever a client makes a request for a certain path or file so that you can generate a response on the fly or retrieve resources from unusual places. An HTTP module executes with every client request, letting you implement various cross-cutting features in your application.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course assumes that you are familiar and experienced with Microsoft’s .NET Framework and ASP.NET development tools. You should be familiar with Web development and understand how HTTP and HTML work to produce Web pages for the user. You should have experience writing applications with ASP.NET 4.0 or later Web forms, and be familiar with how ASP.NET processes page requests, and have strong experience with .NET Framework 4.0 or later programming. You should have experience with Visual Studio 2012 for building Web application projects. Experience with building database applications using these tools will be helpful, although not strictly necessary.
