6:55 It´s important to mention that the using keyword in C# does NOT include the entire System.Collection.Generic but just makes it easier to type collection type in that file. Like instead of having to write System.Collection.Generic.Dictionary myDictionary = new System.Collection.Generic.Dictionary(); we can ommit System.Collection and just write Dictionary myDictionary = new Dictionary(); instead.

ACTUALLY USEFUL TUTORIAL???!!! Genuinely there are videos that are hours long and cover significantly less than this. In the first two minutes I felt like I have already learnt much more than I already know, and much more than that guy Programming with Josh teaches me. Okay like legitimately. I didn't even know var was usable in C#, and I feel like something as simple as VAR, which is used something like javascript should be taught by most other tutorials

3:00 You can definitely have a public method in a private class. A public class would be useless otherwise. 4:30 Don't confuse the deconstructor with the destructor (as you called it at first). The destructor method (or finalizer) is defined using the special name ~MyClass.

[@entith]

I very much disagree with what you say about `var` and implicitly typed variables at around 0:55. You make the very bold claim that implicit typing is good without any support of that claim. Implicit typing is a tool, and just like all tools, there are good and bad ways to use it; situations that call for the tool and situation that said tool should be kept far away from. Implicit typing should be used when, and only when, the inferred type is obvious to the reader and should be. If the inferred type is in any way obscured or non-obvious to the reader (for example, when storing the return value from a method or property in another class), the variable type should be explicitly declared. Note I said the reader, not the compiler and not the author. Just because the type is obvious to the author at the time of writing does not mean it will be obvious anyone else or to the author at a later time. Ultimately it is all about legibility. Our code must be legible; illegible code is difficult to maintain and modify. Implicit typing is a tool to make writing code easier, but ease of reading always needs to take priority over ease of writing if the code is to have any longevity.

[@SamRaddan]

amen

[@georgehelyar]

Most C# does still use var, and there are good things about it, like reduced refactoring at the caller if a type changes. The reason it's generally still readable is that the IDE is good at providing the type information. That said it's starting to move back away from var in some places, with nullable reference types and the new keyword e.g. T t = new();

> these days C# developers will almost exclusively use var That's a very dangerous thing to say seeing all the heated discussions that come up everywhere once you say you either want var only, concrete only, or even a mix You used both Destructor and Deconstructor terms for showing Deconstructors, only a small error but Destructors are vastly different from Deconstructors! Aside from that, cool video. I genuinely think this is a good overview!

[@Bunny99s]

When I saw the title I already knew that it would not fulfill it's promise :D. Almost at every point I had something to complain. Though sometimes I might be a bit picky. 00:36 "Each line is ended with a semicolon". Well especially for new users of the language this can be misleading. Not every line has a semicolon at the end but every statement. It's a bit difficult to explain this in easy terms, though it's certainly not every line. Common beginner mistakes is putting a semicolon at the end of an if statement which would end the statement right there. So the following body has no connection to the if statement this way. 00:46 Besides line comments, there are multi-line comments using /* This is a comment */ 01:26 Just like to point out that the primitive type list is a bit longer than what was shown here ^^ 01:39 Well, he said DATA-types so we might forgive missing enums, delegates, interfaces and closures. 02:01 This is a common misconception. Structs don't live on the stack unless their variable is declared on the stack. Structs are value type and as such are directly stored in the memory of the variable itself. So it depends on where the variable is stored. When the variable is a field of a class, that struct would live on the heap. 03:00 This is just false. A private class can of course have a public field or method. How would you interact with anything in that class? When a nested class is declared private, it can only be used inside that class and can never be exposed to the outside. So you can not declare a public or ptotected field of your private class type since from the outside or a derived class, that nested class would not be visible. However the fields and method inside the private class can have the full spectrum of modifiers 05:20 Those unfamiliar with C# probably should know about logical and, or, xor and not operators which are &&, ||, ^ and ! respectively. Personally I get some itching when tutorials show boolean variables inside an if statement compared to true. An if statement simply requires a boolean value. Those logical operators will return / produce a boolean expression. However a comparison with true is completely unnecessary. You could also do if (aBoolVar == true == true == true) which does the same as if (aBoolVar). The comparison of boolean operators don't need to be used inside an if statement. You can also use them to assign a boolean value. bool myVar = someString == "Hello" && age > 18; 05:57 This is called a "switch expression" which actually evaluates to a value. A switch statement is actually a control flow statement which does not evaluate to anything, like an if statement or for loop. 06:49 Even though I don't like them because they have a lot of overhead, it should be mentioned that you can have multidimensional arrays as well. They may look useful, but the performance isn't that great. For every access it has to do a bounds check on each dimension / index and calculates the flattened index every time. In most cases, especially in time critical situations (when you create games and not business apps) just using a normal 1d array and calculating the index yourself can be way faster as you usually would use nested for loops and you can pre calculate some of the offsets in the outer loops. Also when it's a 1d array it's much easier to iterate over all elements regardless their spatial relationship. 06:55 Small mistake here. The System.Collections namespace does only contain the untyped / object variants of those collections. All the types shown there are inside the System.Collections.Generic namespace. You almost never want to use the untyped variants. They are essentially an ancient leftover. Even when you want to store System.Objects / objects, most people would still use the generic List with the type object rather than the ArrayList. 06:58 It should be pointed out that "importing" a namespace does not load anything like in other languages where some kind of import would actually load or embed another file. Such a using directive will "just" shorten the type names. So this is a pure organisational feature. We use namespaces to avoid name collisions. Different namespaces can have the same class / type names, but you can not "import" both as when you get a name collision, the compiler would complain as it can't tell which type you wanted to use. It's possible to "import" or resolve individual types by: using MyType = Some.NameSpace.MyType; Here we can even rename / give the type a file wide alias name 07.23 This is only partly true as the foreach loop does first and foremost use pattern matching and only resort to the IEnumerable interface when no pattern could be found. The pattern the compiler looks for is simply if the instance passed into the foreach has a method GetEnumerator and if the returned type has a MoveNext method that has no arguments and returns a bool, and it should have a Current property that is readable. If those conditions are met, the compiler will just use those methods, even without the interface. Most of the built-in collection types use struct enumerables / enumerators to avoid creating garbage on the heap. 07:34 Again, the generic version of the IEnumerable is in the System.Collections.Generic namespace. The untyped / object version is in the System.Collections namespace. 08:44 Just to use the right terminology, the stuff after the "where" keyword is called constraints. Several constraints can be specified by separating them with a comma. Note that all constraints need to be satisfied. If a generic class or method has more than 1 generic argument and you want to put constraints on more than one, you need to use another "where" for each argument you want to constrain. Just as a warning: Generics can be quite useful, but are often misunderstood. Many want to use them like polymorphism, however generics are somewhat the opposite of that. While deriving from a base class keeps the data of the base class but allows to overwrite functionality, generics actually keep the functionality the same while being able to exchange the data the function works on. Bound generic classes are usually incompatible with each other. So a List and a List are two completely separate types. In rare cases there can be exceptions with the right conditions (covariance / contravariance) but that are really rare usecases. 08:55 Well a lot is missing for it to be a video about all language features ^^. I know it can't really be comprehensive, but things that weren't really mentioned are: delegates (essentially typed function pointers), anonymous methods / closures, (ability to automatically capture variables in a scope object) lambda expressions, enums, nameof, all operators (there are a lot) operator overloading in classes type conversion operators events, CIL and the ability to decompile to other .NET languages extention methods, linq (I mean the LINQ syntax which is simlar to SQL, not the classes from the System.Linq namespace), attributes (essentially static metadata that can be attached to almost everything) params (essentially allows variable arguments as the last parameter of a method) exceptions (try / catch / finally) object initializer nullable types partial type declarations ref / out (pass by reference) indexer (allows a class to be used like an array or dictionary) using statement (not to be confused with the using directive at the top. It's used to automatically dispose objects) goto (Yes, C# has goto. Now forget that I mentioned it ^^) reflection Those are just some things of the top of my head. I only focused on language feautes, not framework features or classes. Now I've spend already too much time on this post so lets wrap it up. There's still a lot missing. If you want to learn more about the syntax, look up "C Sharp syntax" on wikipedia.

[@vorpal22]

What if you have a mutable type in a record, like an array? I assume you can change that? Asking as a functional programmer. Interesting about the => notation. Is there no final / const keyword? Is that to take the place of final / const? That's rather unusual that instead of returning a tuple of values, the deconstructor actually includes the values in the parameters. How does that work if you don't care about one of the values? I find the PascalCase / CamelCase a bit off-putting, as I do the C-style convention of putting the opening brace on its own line... it just takes up so many more lines of code than putting it on the line where the class / method / etc. is declared. Can methods be declared with a var return type to have auto type deduction? How in-depth is the pattern-matching? Again, as a primarily functional programmer, some languages have really amazing pattern matching abilities. Don't worry about answering these... it's just me thinking out loud. This was an awesome video. I just got the Functional Programming in C# 2nd ed book from Manning to jump in feet first, but having never really used C# before (although knowing Java, Kotlin, and Scala well), this has been a really handy introduction to cover the basics that may well get me up to speed to the point where I can read the book without needing to go through a beginner text. And yes to Rider! I love me some JetBrains and buy the yearly subscription. CLion is the only C++ IDE that I can not only tolerate, but actually enjoy using.

[@adamkis7137]

What about events, actions, tuple...? :)

[@AndreasToth]

Usually constructors and *destructors* are introduced alongside each other and not constructors and deconstructors. For one, many have heard of constructors and destructors but few may have heard of deconstructors and, as such, may not realise the subtle difference in the names and think the syntax demonstrated applies for destructors and not deconstructors! In fact, destructors are not even covered which makes it even less obvious that there is a difference!

[@traintocode]

Constructors and deconstructors are about turning variables into a class and turning classes into variables, so I thought they fitted together. I've rarely seen *destructors* actually used so didn't bother including them.

Value types like structs, enums...numbers, boolean are struct types. Reference types like class, records, delegates, interfaces. Then you talk about functions and how they work in each or all types and what those functions do, access modifiers, return, generators, generics, coroutines, out, ref, varags, events, anonymous functions. This will make the bulk of the video. Then collections: arrays, lists, linkedlists, dictionaries, sets, stacks, queues. Finally, if necessary the compilation and runtime directives like control flow, threads, using keyword, exceptions, macros, unsafe code... And it is done...

Just a note for all the viewers. Records do not necessarily have to be declared "record MyRecord(string prop1, int prop1);". They can be also be declared with curly brackets in the same syntax as classes and structs. The syntax above is called a "primary constructor". It basically writes the property declarations and constructor initializations for you. Records were the first feature to have this and it's idiomatic to always write them like this but as of C# 12 you can use primary constructors on classes and structs too

Maybe I’m the only one here but I hate implicit typing with a passion. Why would I ever want to put a barrier up for knowing what type I’m dealing with? It feels to me that except in a few situations where you could get different types being returned to you and this gives you an option for how to handle that, that I’m always better off making the effort to be explicit in my use of types as it’s far clearer to read?

[@jez9999]

The worst thing is that they ruined the var keyword with respect to nullable reference types. Instead of introducing a separate "var?" statement to be explicit about a variable being able to hold null, they caved in to some people who wanted var to just always be nullable. Now, technically every variable declared with "var" is nullable in a nullable reference type context and will display as such when you hover the mouse over it.

[@diadetediotedio6918]

It's okay, you can hate it all you want, it does not makes what you say true. My point is that knowing the type should not be more important than adhering to the contracts you put in your code using the types, and I don't think this is much of a "barrier" as you can pretty much still see the types.

I hate var. its such a stupid thing to do and just makes it that little bit harder for someone else to glance at your code and know what is going on.

Really!! I would just expect this message from an entry level .Net developer!

You lost me as soon as you mentioned class. This is so far removed from vb6, pascal or even traditional C. Is it so wrong that some people just want to write simple programs without all this high brow theory?

[@collinsonOga]

It's a lot like java. Maybe too much like Java

[@EasternBoss]

Why C# is more complicated that C++ ?

[@tr4spyable]

is it?

[@early20s18]

That's not every feature.
