Overview of this book

Multi-core processors are synonymous with computing speed and power in today’s world, which is why multithreading has become a key concern for C# developers. Multithreaded code helps you create effective, scalable, and responsive applications. This is an easy-to-follow guide that will show you difficult programming problems in context. You will learn how to solve them with practical, hands-on, recipes. With these recipes, you’ll be able to start creating your own scalable and reliable multithreaded applications. Starting from learning what a thread is, we guide you through the basics and then move on to more advanced concepts such as task parallel libraries, C# asynchronous functions, and much more. Rewritten to the latest C# specification, C# 6, and updated with new and modern recipes to help you make the most of the hardware you have available, this book will help you push the boundaries of what you thought possible in C#.

Tweaking the execution of tasks with TaskScheduler


This recipe describes another very important aspect of dealing with tasks, which is a proper way to work with a UI from the asynchronous code. You will learn what a task scheduler is, why it is so important, how it can harm our application, and how to use it to avoid errors.

Getting ready

To step through this recipe, you will need Visual Studio 2015. There are no other prerequisites. The source code for this recipe can be found at BookSamples\Chapter4\Recipe9.

How to do it...

To tweak task execution with TaskScheduler, perform the following steps:

  1. Start Visual Studio 2015. Create a new C# WPF Application project. This time, we will need a UI thread with a message loop, which is not available in console applications.

  2. In the MainWindow.xaml file, add the following markup inside a grid element (that is, between the <Grid> and </Grid> tags):

    <TextBlock Name="ContentTextBlock"
    HorizontalAlignment="Left"
    Margin="44,134,0,0"
    VerticalAlignment...
