[@TDenis-youtube]

Output: the developer who wrote this code will be fired

Maybe in your company 🔥

the `+=` operator is used to combine the delegates so the output will be Check out MMA Check out PCA Stay awesome!

​@@MilanJovanovicTechI thought their adresses in memory would add up together

[@clouds187]

All 3 would be printed im pretty sure :)

[@MilanJovanovicTech]

[@iyerpram]

All 3 would be printed as it is a delegate

[@markdibeh]

I think it gonna return a List> . It should print the three console. But I am not sure abt the return type

[@MilanJovanovicTech]

Prints it all out

[@GekoPoiss]

in FP terms, it's the equivalent of combining instances of IO monads with the sequencing operator (>>) - e.g. `putStrLn "Hi 1" >> putStrLn "Hi 2"`

[@MilanJovanovicTech]

Cool 👌

All the assigned functions will run

[@mazingguitar]

Still it's sorta funny as when you check for type it's System.Action. What happens under the hood?

Here is Action delegate. Thus three writeline methods are called

[@MilanJovanovicTech]

[@yiliang9702]

delegate supports +=opetator. all of the funtions will be triggered.

[@MilanJovanovicTech]

[@rusektor]

All 3 will be run thanks to broadcasting 😊

@@MilanJovanovicTech It's also interesting: when I write the following code, Visual Studio squiggled last line with warning "Dereference of a possibly null reference": Action del1 = () => Console.WriteLine("Task 1"); Action del2 = () => Console.WriteLine("Task 2"); Action del3 = () => Console.WriteLine("Task 3"); var func = del1; func += del2; func += del3; func(); Console.WriteLine("remove del2..."); func -= del2; func(); I then realized that this is due to the fact that there can be a situation when there will be no delegates to run. The solution is simple: func?.Invoke(); 😉

[@sameerband2933]

All three methods would be executed. We have event to enforce multicast delegate so that we don't accidently assign a delegate instead of subscribing. I. E. Enforce += and prevent =

[@dinorme]

easy, its a delegate so it will print 3 of them :3

[@MilanJovanovicTech]

[@mohammadkalbouneh7892]

All three right?

[@MilanJovanovicTech]

Yes

[@codingwithgyver1637]

seems just what a delegates do for append actions

[@MilanJovanovicTech]

Indeed
