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

Using PerfTips to identify bottlenecks in code


PerfTips are definitely one of my favorite features of Visual Studio 2015. Explaining what they do doesn't do them justice. You have to see them in action.

Getting ready

Do not confuse PerfTips with CodeLens. PerfTips is a separate option from CodeLens in Visual Studio.

How to do it…

  1. PerfTips are enabled by default. But just in case you are not seeing any PerfTips, go to Tools | Options, and expand the Debugging node. Under General, to the bottom of the settings page, you will see an option called Show elapsed time PerfTip while debugging. Ensure that this option is checked:

  2. We will create a few simple methods that mimic long-running tasks. To do this, we will just sleep the thread for a couple of seconds. In the Recipes.cs file, add the following code:

    public static void RunFastTask()
    {
        RunLongerTask();
    }
    
    private static void RunLongerTask()
    {
        Thread.Sleep(3000);
        BottleNeck();
    }
    
    private static void BottleNeck()
    {
        Thread.Sleep(8000...
