This course is better than 2 or 3 paid ones I have done, again thanks Julio for sharing this with the community. Hugs from Brazil.

Thank you, I'm glad you think so!

Julio you are a great teacher!! I have reached up to 90min in this video which is the first of your series for me and I really enjoy learning from you!! You are a star my friend!! Keep on teaching us!!! Thanx a million for your video!!

[@juliocasal]

You're very welcome!

[@user-jt3nr7ci8p]

Excellent ! Not too easy and not too much. Thank a lot.

[@juliocasal]

Glad you liked it!

[@jishh7]

Cant even explain how great the lessons are. You actually go into detail on how things are connected, setup, and most importantly what they mean. I have seen too many videos where they say, "add this" and I have to pause the video and watch another or find out on my own what something is doing which throws me off my process and flow. Just got to the point in the frontend tutorial where you sent us here and am soo excited to get more knowledge on building my own rest API as a few companies I have talked to asked me if I have built my own before.

Thank you for posting such a great content, I have a question if you do not mind, in most of the courses I've seen for asp net core, they used visual studio instead of visual studio code, is there any major differences between using vs or vs code for asp net core ?

VS is more feature rich, VS Code is much more lightweight.

thanks so much for the tutorial. but there's a question i wanted to ask, why are the properties of the request body turned pascal case when you accessed them in the route handler functions eventhough they were in camel case originally?

ASP.NET Core default serialization logic takes care of that.

The Set method creates a DbSet that can be used to query and save instances of Game. By doing Games => Set() you are assigning the result of the Set method to the Games property.
