C# 7 and .NET Core 2.0 High Performance PDF

Preface

The book begins with an introduction to the new features of C# 7 and .NET Core 2.0, and how they help improve the performance of your application. The book will then help you understand the core internals of .NET Core, which includes the compilation process, garbage collection, utilizing multiple cores of the CPU to develop highly-performant applications, and measuring performance using a powerful library for benchmarking applications named BenchmarkDotNet. We will learn about developing applications and programs using multithreading and asynchronous programming, and how to use those concepts to build efficient applications for faster execution. Next, you'll understand the importance of data structure optimization and how it can be used efficiently. We move on to the patterns and best practices to use when designing applications in .NET Core, along with how to utilize memory in an effective way and avoid memory leakage. After that, we'll talk about implementing security and resiliency in .NET Core applications, and we'll use the Polly framework to implement a circuit breaker, and retry and fallback patterns, along with certain middleware to harden the HTTP pipeline. We'll also implement security such as authorization and authentication using the Identity framework. Moving ahead, we will learn about the microservices architecture and see how we can use it to create applications that are modular, highly scalable, and independently deployable. We end with App Metrics, and will learn how to use it to monitor the performance of your application.

Who this book is for

This book is for .NET developers who want to improve the speed of their application's code or who simply want to take their skills to the next level, where they can develop and produce quality applications that are not only performant but also adhere to the industry best practices. Basic C# knowledge is assumed.

What this book covers

Chapter 1, What's New in .NET Core 2 and C# 7?, discusses the .NET Core Framework and covers some improvements that were introduced with .NET Core 2.0. We will also look into the new features of C# 7 and see how we can write cleaner code and simplify syntactic expressions. Lastly, we cover the topic of writing quality code. We'll see how we can leverage the Code analysis feature of Visual Studio 2017 to add analyzers to our project and improve code quality.
