Still churning out new videos and immediately responding to comments from 3-year old videos :-) You're a credit to the community! Thanks for the videos and keep up the good work.

I have watched a few videos about calling API's. And I originally skipped this one because of the length, and I was so anxious to get started. After taking the time to watch it, I regret skipping over it. This video was so informative, and Tim really has a way of explaining everything very thoroughly. I am now a fan, and will be watching as many of your videos as possible. Thank you for taking the time to create these videos.

As a newbie to coding in general i appreciate the advice on the comic model. Just specifying the properties you need is golden nuggets. I’m always like ‘give me all the things magical internet box’ and I’ll figure out what I need, whilst my program grinds to a halt. Thank you Tim Corey for knowing what I need before I do.

I just started my first ever api project at work. This video really saved me. Very clear. Tremendously helpful.

[RickGtr]

Luckily I found this video. You're the only one who can describe these techniques in an organized way. I just subscribed to your channel too.

[hachadwick]

I wish I could "like" this video more than once. You are a great teacher.

[DameLyf]

I've been confused about API and integrating with C#, watched various videos about this subject and was still lost, your explanation has made it more clear. Thanks for your tutorials - looking forward to the continued courses.

[romedov]

I wondered how to connect to a web API for a long time. I sought out for the resolution for a long time and I couldn't understand anything until I've watched this video. Thank you a lot, sir.

[milanstraka]

Great video, one of the best on YouTube when it comes to C#

[shubhamsahrawat]

I am probably a crappy starting up programmer who rarely subscribes to channels and rarely ever likes videos. For you I make an exception, this video was super helpful and this kind of content is rarely ever free. Thank you and God Bless the beard.

[alilubab]

That's an amazing and hard to find sort of tutorial on youtube, thank you!

[RAM-ffdy]

Great Video Tim, I always wait for your new videos, can you make a video on Serialization and Deserialization, Thanks

[CRBarchager]

I just got an assignment for a job where I had to do exactly this and it helped me alot. Thank you!

[patrickbacon]

Thank you! I really appreciate how you have given back to the c# community.

[alexanderrupp]

I don’t really comment often but I just want to say thank you so much. You have been a really big help on a side project I’m working on and you explained everything so well!

[madhusaivemulamada]

Thanks Tim, these concepts helped me in an interview

[filipzeman]

Did this in generics because of knowledge from your other video about generics. Thank you, always happy to take a challenge when you suggest something extra.

[vinuhosanagar]

Thank you Sir. Can you please do a video on serialization and deserialization in C# may be considering a wpf datagrid serialized into XML. I found
many examples, but when you explain it will be complete for sure
