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.

Name: C# Performance Fundamentals.

Format: Self-paced.

Content: training lectures, video lessons, quizzes and coding exercises.

Requirements: a Windows, Mac or Linux laptop with Microsoft Visual Studio or Visual Studio Code.

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

This Training
Self-Paced Training
Guided Training
Classroom Training

What is included in this training?

You will receive lifetime access to training lectures, video lessons, quizzes and homework assignments.

How long will it take me to complete this training?

For a self-paced and guided training, you can spend as much or as little time you want on the lectures and labs. It’s entirely up to you how long you take to complete the training. For a classroom training, we will complete all of the training content and labs together in 3 days.

How long do I have access to the training content?

You have lifetime access to all training content.

What do I need for this training?

You’ll need a Windows laptop (or other operating system running a Windows virtual machine) with a recent version of the NET Core Framework and the Visual Studio Code editor installed. You will also need Microsoft Teams if you’re attending the live classroom training.

For which certification does this training prepare me?

This training is not part of an official Microsoft certification path, but you can use it to prepare for the Azure Data Scientist or Azure AI Engineer certifications if you like.

What is a self-paced training?

In a self-paced training, you 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.

How am I supported in a self-paced training?

I will support you in a private Slack channel. You can ask me anything you want anytime you like, and I will respond as soon as I’m able to. I typically respond in 2-3 hours but it can take a little longer if we are in different timezones.

Who should attend a self-paced training?

A self-paced training is ideal for tech professionals who can work independently and only need a little support throughout the training to learn the content and complete the lab exercises.

My colleagues and I want to sign up as a team and learn together. Is this possible?

No, self-paced training is only for individual students who each learn at their own pace. Please consider a classroom training instead.

What is a guided training?

In a guided training, you study the training lectures and work on the lab assignments in your own time and at your own pace. We will also spend some time together in a series of Microsoft Teams calls in which I will support you with the training lectures and the lab exercises and help you get ready for the certification exam.

How am I supported in a guided training?

I will support you in a private Slack channel, and you can also book an unlimited number of 1-hour Microsoft Teams support calls with me. In these calls, I will support you with the training lectures and the lab exercises and help you get ready for the certification exam.

Who should attend a guided training?

A guided training is ideal for tech professionals who prefer a healthy mix of guidance and independence with an average level of support throughout the training to learn the content and complete the lab exercises.

My colleagues and I want to sign up as a team and learn together. Is this possible?

No, guided training is only for individual students who each learn at their own pace. Please consider a classroom training instead.

What is a classroom training?

A classroom training is a live event in which I will present the training lectures, help you complete the lab exercises and get you ready for the certification exam. Classroom trainings are conducted online in full-day Microsoft Teams calls held during business hours in the Central European timezone. You will be sharing the classroom with other students and learn together as a group.

When and where is classroom training conducted?

Classroom trainings are conducted online during Central European business hours. You will receive a Microsoft Teams link when you sign up for a class. Please note that classroom trainings can also be held on-site at your place of work. Please book a discovery call with me if you’re interested, and we can discuss your requirements.

How am I supported in a classroom training?

I will continuously support you live, because we’ll both be in the same virtual classroom together.

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.

My colleagues and I want to sign up as a team and learn together. Is this possible?

Yes, absolutely. Please book a discovery call with me to discuss your requirements. I can offer group discounts to business teams.
