Course description

Get a quick recap of what ASP.NET Core is all about and dive into the details of the anatomy of a web application. Take a look at the standard structure of a project, exploring the most important code files that you’ll include in most applications. Drill down into the details of services and middleware that define the request pipeline and the role of the Startup class in ASP.NET Core. Although this is a part of the new technology that is fundamentally different from how an application started in classic ASP.NET, this course covers everything you need to know to feel comfortable starting to implement it in your projects.


This course assumes that students have some programming background, and at least minimal experience with classic ASP.NET, C#, and Visual Studio. As with any such course, the more experience you bring to the course, the more you’ll get out of it. This course moves quickly through a broad range of programming topics, and is focused on using the .NET Framework with C#. The course also assumed that you are well familiar with how to use the version of Windows that you are running. For example, the course might say simply “open a browser” without explaining how to do that. You should also be able to navigate the folder hierarchy using Windows Explorer.
