Introduction to C# performance 

This course will teach you how to speed up your C# code with performance tricks that every professional developer should know.

You’ll learn the fundamentals of the .NET Framework, how the Garbage Collector works, the difference between the stack and the heap, what boxing and unboxing is, and much more!

I’ll even give you a crash course in Intermediate Language so that you can actually read the machine language produced by the C# compiler. We’ll compile a couple of code snippets, take a look at the IL code and see if we can make any improvements.

Training Details

This course will teach you how to speed up your C# code with performance tricks that every professional developer should know.

You’ll learn the fundamentals of the .NET Framework, how the Garbage Collector works, the difference between the stack and the heap, what boxing and unboxing is, and much more!

We’ll also look at array performance, using pointers in C# to manipulate memory directly, and a neat trick to place an array in stack memory for extra performance. 

Throughout the course we will be compiling C# code snippets into Intermediate Language, and then inspecting the compiled code for performance bottlenecks. You’ll learn how to interpret basic IL instructions and read machine code directly.

Sneak Preview

In this complimentary training lecture I will teach you how to optimize arrays in C#. We’ll look at 1-dimensional arrays, multidimensional arrays and jagged arrays and compare the performance of all three. You will also learn a technique called Array Flattening to speed up 2-dimensional arrays.

Frequently Asked Questions

  • Classroom Training
  • Microsoft Training
  • Online Training
  • Misc
What is a classroom training?
A classroom training is a live event in which I will present the training lectures and help you complete the lab exercises. You will be sharing the classroom with your colleagues and learn together as a group.
Where is a classroom training conducted?
Depending on your needs, classroom trainings can be conducted on-site at your place of work, in a fully-equipped classroom at a training agency, or online in a multi-day Microsoft Teams or Zoom session.
Who should attend a classroom training?
A classroom training is ideal for tech professionals who can commit to full days of learning and want to learn together as a group.
How am I supported in a classroom training?
I will continuously support you live, because we’ll both be in the same physical or virtual classroom together.
What is a Microsoft training?
A Microsoft training is an official classroom training course from the Microsoft training catalog that will teach you essential tech skills and prepare you for a certification exam.
What's included in a Microsoft training?
You will receive online course content, access to an Azure sandbox environment, lab exercises, a practice exam and an exam voucher.
How long do I have access to a Microsoft training?
You have unlimited access to the training content, 180 days access to the lab environment and 30 days of access to the practice exam. The exam voucher is valid for a year.
How can my team and I attend a Microsoft training?
Please provide your requirements in the form on the training pages and I will contact you as soon as possible to plan and set up your training.
What is an online training?
In an online training you can study the training lectures and work on the lab assignments in your own time and at your own pace. You can spend as many or as little hours per week as you want on the training. This training format is ideal for tech professionals who have irregular work hours and cannot commit to a classroom training.
What's included in an online training?
You will receive prerecorded online video lectures, text lectures, multiple-choice quizzes and homework exercises.
How am I supported in an online training?
You are supported through email, and you can also book a 30-minute video support call with me if you want. I will help you with the training lectures and lab exercises and get you ready for your certification exams.

Are you a certified trainer?
Yes. I started classroom training in 1997 and obtained my Microsoft Certified Trainer (MCT) credential in 2005. I currently have more than 25 years of training experience.
What is the maximum size for a classroom training?
It depends on the size of the classroom, the team and the complexity of the subject. But typically, groups of up to 15 students work best. If you have a larger group, it's best to split them over multiple training sessions.
Can you provide training in a non-English language?
Yes, I am fluent in English, Dutch and German thanks to a multilingual upbringing by my international family. I can provide any training in all three languages.
Will you travel to my country to provide a classroom training?
Yes. I am based in Amsterdam and often travel abroad to provide classroom training in other countries. I love meeting my students on-site, no matter where they live.
