Course Description


Last updated: November 17th, 2017 - Added new promo video
Modern computers have loads of memory. But it's very easy to burn through it all in seconds if your code is not efficient about allocating and using memory.
Did you know that one simple mistake can make your code allocate 1600 times more memory than absolutely necessary?

Don't be 'that developer' who keeps crashing the development server with an OutOfMemory exception!
And you certainly don't want to be responsible for inflating the hardware budget. Can you imagine having to explain to your team that 512 GB of memory is not enough to run your code on the production server?

Let me help you.
It doesn't have to be like this. If you have a good understanding of the garbage collection process and follow a few simple best practices, you can dramatically reduce the memory footprint of your code.

Sound good?
In the last 10 years I have learned the secrets of garbage collection in .NET, and in this course I am going to share them all with you.
In a series of short lectures I will take a detailed look at the garbage collection process. I will show you all of the memory allocation problems you can expect when writing C# code, like unexpected boxing, string duplication, collection resizing, and more. I'll teach you quick and easy strategies to resolve these problems.
By the end of this course you will be able to master the garbage collector.
Why should you take this course?

You should take this course if you are a beginner or intermediate C# developer and want to take your skills to the next level. Garbage collection and memory management might sound complicated, but all of my lectures are very easy to follow and I explain all topics with clear code and many instructive diagrams. You'll have no trouble following along.
Or maybe you're working on a critical section of code in a C# project, and need to make sure your memory usage is as efficient as possible? The tips and tricks in this course will help you immensely.
Or maybe you're preparing for a C# related job interview? This course will give you an excellent foundation to answer any questions they might throw at you.
30 day money-back guarantee

I learned a lot. I had no idea when I was using string concatenation stead of StringBuilder append.

Simple, great explanations, loved the chalk board idea, very useful and easy to absorb

Great, in-depth and well explained how it all works in the background. Comprehensive knowledge about Garbage Collector and memory management. Highly recomended course of type "must have".

By Sathish kumar on 4 months ago

Outstanding course content and content delivery was good with complete picture. I recommend each and every C# developer should go through this course to stand out from the crowd.

I thought the course was good.Usage of mono wasn't great, there is no windows version available (have fun building from source) so I had to do the hard yards with VS and dotMemory to verify the lecture results.Verifying the results/actual memory allocation took a bit of work as the lectures demonstrated the overall concept but not a 1:1 reconciliation of the memory usage for the topic being discussed. Personally I like to 'do' and part of that is getting the numbers to line up.

I really enjoyed this course and learned many interesting things about how to make my C# code more efficient with memory and to work friendlier with the Garbage Collector. I will use these tips to make my code more efficient instead of just coding like every other developer out there.

By Andrew Jakobs on 5 months ago

It's a great course on optimisations in regard to memory (and in result also speed). But having done the course 'C# performance tricks: How to radically optimize your code' before this course, I think it's a bit of a rip-off (don't know which course came first), because I think about 85% of this course is also used in the performance course.. I would suggest to combine both courses into one and drop the two separate courses..

By Vilas Talwekar on a month ago

Memory concepts are much clear now. Thank You!

By Emily Senft on 3 months ago

Clearly knows his stuff and gets it across well. Clear and concise!

By Alberto Gonzlez Balderas on 6 months ago

This course is great! The way of explain is clear and the tips are very useful.

By Subbulakshmi on 7 months ago

It gave a lot of insight on how the .net framework manages the memory. The course was easy to follow with simple examples

By Ali Aligiller on 2 months ago

It is very efficent course. It is worth.
