ASP.NET Core 2 High Performance - Second Edition

By: James Singleton

Overview of this book

The ASP.NET Core 2 framework is used to develop high-performance and cross-platform web applications. It is built on .NET Core 2 and includes significantly more framework APIs than version 1. This book addresses high-level performance improvement techniques. It starts by showing you how to locate and measure problems and then shows you how to solve some of the most common ones. Next, it shows you how to get started with ASP.NET Core 2 on Windows, Mac, Linux, and with Docker containers. The book illustrates what problems can occur as latency increases when deploying to a cloud infrastructure. It also shows you how to optimize C# code and choose the best data structures for the job. It covers new features in C# 6 and 7, along with parallel programming and distributed architectures. By the end of this book, you will be fixing latency issues and optimizing performance problems, but you will also know how this affects the complexity and maintenance of your application. Finally, we will explore a few highly advanced techniques for further optimization.

The new .NET


The new ASP.NET and the .NET Framework that it relies upon were rewritten to be open source and cross-platform in Core version 1. The packages were also split up, which although done with admirable intentions has caused confusion. ASP.NET Core 2 is now included in the .NET Core 2 installation package along with Entity Framework Core. This means that you no longer need to ship the ASP.NET Core framework with your app when you deploy. The project known as .NET Native has been postponed (outside of UWP) and will hopefully arrive within the next year.

All these different names can be perplexing, but naming things is hard. A humorous variation of Phil Karlton's famous quote goes like this:

"There are only two hard things in Computer Science: cache invalidation, naming things, and off-by-one errors."

We've looked at naming here, and we'll get to caching later on in this book.

It can be a little confusing understanding how all of these versions fit together. This is best explained with...
