    All this await stuff in C#

    I've not MT code in C# for years and when I did it was all the old-fashioned way... basically signals and threads and stuff like in C++.
    The asynchronous revolution broadly passed me by and now I'm writing a MT application... it feels a great opportunity to bone up on the modern way but online resources are muddled depending when they were written.

    Can anyone recommend a book on modern C# for someone who has worked with it but is out of date with this stuff?

        Books are old school but as everyone has their own level of experience, goals, and desire for learning just google 'c# books' and see what is currently recommended for the level you feel you're at.

        Alternatively start at the beginning as a refresher by binge watching the following:

        c# tutorial for beginners

        102 videos. Shows how the language is broken down so you can seek out more advanced videos or courses for any aspects of particular interest. The 'await/async' stuff is covered in video 101.
        Maybe tomorrow, I'll want to settle down. Until tomorrow, I'll just keep moving on.

          Unless you are doing web page handling, my advice is to not use the await stuff and just do your multithreading the old school way, create and manage your own threads.

          Others will disagree of course.

              OK, you also have to scroll a bit to read it, but nothing’s perfect
