Choosing to learn and develop with a new framework is a big investment, so it’s important to establish early on whether it’s right for you. In this chapter, I provide some background about ASP.NET Core: what it is, how it works, and why you should consider it for building your web applications.
If you’re new to .NET development, this chapter will help you to understand the .NET landscape. For existing .NET developers, I provide guidance on whether now is the right time to consider moving your focus to .NET Core and .NET 5.0, and on the advantages ASP.NET Core can offer over previous versions of ASP.NET.
ASP.NET Core is a cross-platform, open source, web application framework that you can use to quickly build dynamic, server-side rendered applications. You can also use ASP.NET Core to create HTTP APIs that can be consumed by mobile applications, by browser-based single-page applications such as Angular and React, or by other backend applications.
