“Finished the marathonian @dotnetosorg #AsyncExpert course. Thank you so much @konradkokosa @Scooletz @lukaszpyrzyk !!!! I now have a very good low-level explanation on how the async and concurrent magic work under the hood.”

“Thanks @dotnetosorg for deep dive into asynchronous programming! Ten weeks of great explanations, tips n tricks and motivation to learn more. It was definitely worth it! Looking forward for memory management course #asyncexpert.”

“Finished the async expert course from
@dotnetosorg. I know more than I did, I have more to learn, but I know where to look, when I need to look. It’s going to take time to embed but glad I took the course.”

“If you write .NET code, then the https://asyncexpert.com training is worth every euro. I can't recommend it strong enough. I'm still in the first parts but what I learned already paid off, and I've been in .NET for 20 years...
@konradkokosa and the rest of the team are AMAZING”
