C# Multithreading Basics | Free Udemy Course

A brief introduction of this course.

A brief introduction about the tutor of this course.

The instruction to download and install Visual Studio 2022 Community.

Source codes are attached to each video. But download the full sample from a GitHub repo is also available.

Create the WPF UI which will be used throughout the rest of the entire course.

Create two methods to test string concatenation speed and memory resource consumption. One method concatenates a string type variable 50,000 times, and the other appends new strings to a StringBuilder object 50,000 times. The comparison result is quite shocking!

A brief and easy to understand explanation of the differences between the two string concatenation methods. You will learn when to use string or StringBuilder. The differences between memory stack and memory heap are also explained in this video.

The conceptual structure of different multi-threading techniques is introduced in this video. Including Thread, ThreadPool, Task, TaskFactory, Parallel, Async and Await, BackgroundWorker and Dispatcher.

Introduction of how to use BackgroundWorkers to perform long-running tasks behind the user interface and the pros and cons of using BackgroundWorkers.

Use the Dispatcher and DispatcherTimer to replace the functionality of the ProgressChanged event of a BackgroundWorker to update data to the user interface during the program execution. The UI data binding technique of WPF is also used with Dispatcher.

Introduction of how to use Thread and ThreadPool to achieve the same purpose of what we did in the last few lessons.

This is the first video regarding the Task Parallel Library (TPL). Introduction of how to use Task class to achieve the same purpose of concatenation a string 50 thousand times and measure its execution time and total memory consumption. The most frequently used Task. Run and Task. Factory. StartNew are explained in this video.

This is the second video regarding the Task Parallel Library (TPL). Introduction of how to use async and await modifiers to achieve the same purpose of concatenation a string 50 thousand times and measure its execution time and total memory consumption is explained.

This is the third video regarding the Task Parallel Library (TPL). Introduction of how to concatenate a string 50 thousand times parallelly by using Parallel. For , and then measure the execution time and total memory consumption is explained.

A brief summary of what has been mentioned and things that are not covered in this course are introduced in this video. An ultimate demo of running four different types of multithreading applications is demonstrated at the end of this video. The source code of that ultimate demo is also included in the resource folder.
