Great video on a difficult topic. Thanks!

Never use `Wait`, I agree. That also applies to `Result` and a few other blocking methods. Great explanation. Hope you can dive into the ‘promise of completion’ pattern next. It’s a little understood behind the scenes architecture detail.

Thank you for the video. I found it very helpful.

Very good. Better than many others I viewed

Regarding Asyn suffix. Its advisable to add this suffix 1) when you have synchorios version of the same method in the same class 2) if this method is async void then IDE might not help 3) just to increase readability.

The advise on using Task ctor is flawed. There are many scenarios to create not started tasks.... If you don't have any specific requirements to create a task, you don't need to use factory, just use the Task ctor.

there is difference ?

Task firstjobAsync() => secundJobAsync()
To
async Task firstjobAsync() => await secundJobAsync()

there is nothing "under the hood" in this video!!
