By: Dirk Strauss, Fabio Claudio Ferracchiati

Overview of this book

C# has recently been open-sourced and C# 7 comes with a host of new features for building powerful, cross-platform applications. This book will be your solution to some common programming problems that you come across with C# and will also help you get started with .NET Core 1.1. Through a recipe-based approach, this book will help you overcome common programming challenges and get your applications ready to face the modern world. We start by running you through new features in C# 7, such as tuples, pattern matching, and so on, giving you hands-on experience with them. Moving forward, you will work with generics and the OOP features in C#. You will then move on to more advanced topics, such as reactive extensions, Regex, code analyzers, and asynchronous programming. This book will also cover new, cross-platform .NET Core 1.1 features and teach you how to utilize .NET Core on macOS. Then, we will explore microservices as well as serverless computing and how these benefit modern developers. Finally, you will learn what you can do with Visual Studio 2017 to put mobile application development across multiple platforms within the reach of any developer.

Preface

Visual Studio 2017 allows developers to harness the latest technology and create world-class applications across a variety of platforms. The new language features in C# 7.0 are powerful tools that will allow you to write better functioning software and deliver complex business requirements quicker.

The book takes a look at all of the awesome new features in C# 7. It also looks at how developers can write diagnostic analyzers to produce better code and adhere to specific code standards. It explores .NET Core 1.1 and looks at creating an ASP.NET Core application using the MVC framework.

If creating mobile apps is something you are interested in, this book will show you how to do so using Cordova. If you want to create native iOS applications, this book shows you how to do just that using Visual Studio for Mac.

If serverless computing is something that want to understand more, then look no further. In the book, we take a look at what the term serverless computing means. We also look at how to create an Azure function and how to use AWS and S3. Lastly, hot off the press from Amazon, we take a look at using C# lambda functions with AWS.

This book will show you the beauty of C#, which when combined with the power of Visual Studio, makes you a very formidable developer, capable of meeting a variety of programming challenges head on.

Whatever your skill level when it comes to programming with C#, this book provides something for everyone and will make you a better developer.
