    I don't understand the need for constraints on generics. Why would you use that instead of just telling the method what type it is on the parameter in the signature? For instance: public int getSum(int a, int b) instead of public int getSum(T a, T b) where T : int ?

    what keyboard do you use? sounds good

    What would happen at runtime if the Type T didn't have a parameterless constructor and we called DoSomething() to instantiate an object of said T?

    Very clear, concise and thorough. Thanks a lot.

    I like how you narrate what the code / symbols mean – that really helps a lot.
    That is one thing that for me makes C# a real pain – that it is not easy to read at all because instead of words it uses e.g ":" or "#" to mean something. Apart form being difficult to read, you cannot exactly Google : in C# and find out what it is doing.

    If I have a Persons (string name, etc) class to store in a list would it be better practice to use the existing List or make my own generic?

    For me is to fast, i'm a student and this is like more for working people! Also sometimes using shortcuts without explanation.

    I'm new to coding – in general, not only in c#. And you're definitively my teacher – you know what you are talking about. What impresses me the most is that you have obviously some sort of didactics to your thematics. Highly appreciate that! Keep doin vids, they're awesome!

    what function has 'this'  on " Book this[int index]"? and I think it would be good to explain what where T : IComparable is, as it does not look like any other code.

  40. Will Harrison Avatar

    this is only my second video of yours to watch, but I have to say they are very high quality and very well done.  keep up the good work and thanks.
