C# 7 and .NET Core 2.0 High Performance

By: Ovais Mehboob Ahmed Khan

Overview of this book

While writing an application, performance is paramount. Performance tuning for realworld applications often involves activities geared toward fnding bottlenecks; however, this cannot solve the dreaded problem of slower code. If you want to improve the speed of your code and optimize an application's performance, then this book is for you. C# 7 and .NET Core 2.0 High Performance begins with an introduction to the new features of what?explaining how they help in improving an application's performance. Learn to identify the bottlenecks in writing programs and highlight common performance pitfalls, and learn strategies to detect and resolve these issues early. You will explore multithreading and asynchronous programming with .NET Core and learn the importance and effcient use of data structures. This is followed with memory management techniques and design guidelines to increase an application’s performance. Gradually, the book will show you the importance of microservices architecture for building highly performant applications and implementing resiliency and security in .NET Core. After reading this book, you will learn how to structure and build scalable, optimized, and robust applications in C#7 and .NET.

Designing Guidelines for .NET Core Application Performance

Best practices in writing optimized code in C#

There are many factors that negatively impact the performance of a .NET Core application. Sometimes these are minor things that were not considered earlier at the time of writing the code, and are not addressed by the accepted best practices. As a result, to solve these problems, programmers often resort to ad hoc solutions. However, when bad practices are combined together, they produce performance issues. It is always better to know the best practices that help developers write cleaner code and make the application performant.

In this section, we will learn, the following topics:

  • Boxing and unboxing overhead
  • String concatenation
  • Exceptions handling
  • for versus foreach
  • Delegates
