Overview of this book

During your application development workflow, there is always a moment when you need to get out of a tight spot. Through a recipe-based approach, this book will help you overcome common programming problems and get your applications ready to face the modern world. We start with C# 6, giving you hands-on experience with the new language features. Next, we work through the tasks that you perform on a daily basis such as working with strings, generics, and lots more. Gradually, we move on to more advanced topics such as the concept of object-oriented programming, asynchronous programming, reactive extensions, and code contracts. You will learn responsive high performance programming in C# and how to create applications with Azure. Next, we will review the choices available when choosing a source control solution. At the end of the book, we will show you how to create secure and robust code, and will help you ramp up your skills when using the new version of C# 6 and Visual Studio

Creating your Visual Studio project

The Visual Studio project that you will create will be used to add the classes that contain the code samples in each recipe of this book. The project will be a simple console application that will call into static classes that do the work of illustrating the recipe code and outputting the results (if any) to the console window.

Getting ready

To step through the recipes in this book, you will need a copy of Visual Studio 2015. If you do not have a copy of Visual Studio 2015, you can download a free copy of Visual Studio 2015 Community from https://www.visualstudio.com/en-us/products/visual-studio-community-vs.aspx.

You can also compare editions of Visual Studio 2015 by navigating to https://www.visualstudio.com/en-us/products/compare-visual-studio-2015-products-vs.aspx.

After you have downloaded and installed Visual Studio 2015, create a new console application that will contain the recipes illustrated in this book.

How to do it…

  1. Start Visual Studio 2015 and click on the File menu. Then, click on New and then select Project. You can also use the Ctrl + Shift + N keyboard shortcut:
    How to do it…
  2. From the New Project dialog screen, select Console Application, which can be found by going to Installed | Templates | Visual C# | Windows | Classic Desktop in the tree view to the left. You can call your console application CodeSamples:
    How to do it…

    Note

    You will notice that the selected framework is .NET Framework 4.6.1, which is selected by default. Leave this framework selected when creating your project.

  3. Visual Studio now creates your console application, which we will use to create all the code samples needed for this book.

How it works…

This console application will form the base of the recipes in this book. Each recipe can be individually added to this console application. A recipe, therefore, can function on its own without the need to create a previous recipe. You can also easily separate any custom code you might want to add and experiment with. It is also recommended that you play around with the code by adding classes of your own.
