ASP.NET Core 2 High Performance

Learn how to develop web applications that deploy cross-platform and are optimized for high performance using ASP.NET Core 2

About This Book

• Master high-level web app performance improvement techniques using ASP.NET Core 2.0
• Find the right balance between premature optimization and inefficient code
• Design workflows that run asynchronously and are resilient to transient performance issues

Who This Book Is For

This book is aimed for readers who can build a web application and have some experience with ASP.NET or some other web application framework (such as Ruby on Rails or Django). They can be people who are happy learning details independently but who struggle to discover the topics that they should be researching. The reader should be interested in improving the performance of their web app and in learning about ASP.NET Core and modern C#.

What You Will Learn

• Understand ASP.NET Core 2 and how it differs from its predecessor
• Address performance issues at the early stages of development
• Set up development environments on Windows, Mac, and Linux
• Measure, profile and find the most significant problems
• Identify the differences between development workstations and production infrastructures, and how these can exacerbate problems
• Boost the performance of your application but with an eye to how it affects complexity and maintenance
• Explore a few cutting-edge techniques such as advanced hashing and custom transports

In Detail

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.

A step-by-step practical guide filled with real-world use cases and examples

James Singleton is a British software developer, engineer, and entrepreneur, who has been writing code since the days of the BBC Micro. His formal training is in electrical and electronic engineering, yet he has worked professionally in .NET software development for nearly a decade. He is active in the London start-up community and helps organize Cleanweb London events for environmentally conscious technologists. He runs Cleanweb Jobs, which aims to help get developers, engineers, managers, and data scientists into roles that can help tackle climate change and other environmental problems. He also does public speaking and has presented talks at many local user groups, including at the Hacker News London meet up. James holds a first class degree (with honors) in electronic engineering with computing, and has designed and built his own basic microprocessor on an FPGA, along with a custom instruction set to run on it. James contributes to, and is influenced by, many open source projects, and he regularly uses alternative technologies such as Python, Ruby, and Linux. He is enthusiastic about the direction that Microsoft is taking with .NET, and their embracing of open source practices. He is particularly interested in hardware, environmental, and digital rights projects, and is keen on security, compression, and algorithms. When not hacking on code, or writing for books and magazines, he enjoys walking, skiing, rock climbing, traveling, brewing, and craft beer. James has gained varied skills by working in many diverse industries and roles, from high performance stock exchanges to video encoding systems. He has worked as a business analyst, consultant, tester, developer, and technical architect. He has a wide range of knowledge, gained from big corporates to start-ups, and lots of places in between. He has first-hand experience of the best, and the worst, ways of building high-performance software.
