These two men teach me a lot

@dotnet team please continue this series

Glad i came to know about the primary constructors.tks

[@DB42YT]

Easier way to understand OOP than what I was taught.

Class refactoring.
var p = new Person("Kevin", "Velez", 19);
var p2 = new Person("Mario", "Vasquez", 19);
List list = [p, p2];
public class Person(string name, string lastname, int age)
{
public string _name { get; set; }
public string _lastname { get; set; }
public int _age { get; set; }
}

Great tutorial video

[@kuje89]

Thank you!

[@Ricebow11]

What would be the NEXT best playlist to watch after finishing "C# for Beginners"? I definitely learned a lot from those two awesome instructors.

[@marcosphs]

Congratulation 👋

[@jjj-ke9mp]

What’s the difference between
public string First { get; } = firstname;
public string First => firstname;
public string First { get => firstname; }
I know the result might be the same but I can’t see the difference 😢

[@VivekGawande1]

The first one sets a default value for the First property. The second one is a computed property, so it won't be stored in the object, it's calculated whenever we read the property. The last one I guess is similar to the first one

[@bryanpaderes8963]

How to implement this primary constructor in a derived class if its base class has a constructor parameters? I tried this code but it doesn't work:
public class Animal(string name, int age)
{
public string Name { get; } = name;
public int Age { get; } = age;
}
public class Dog(string name, int age, string breed) : base(name, age)
{
public string Breed { get; } = breed;
}
Edit (this is now the new way):
public class Animal(string name, int age)
{
public string Name { get; } = name;
public int Age { get; } = age;
}
public class Dog(string name, int age, string breed) : Animal(name, age)
{
public string Breed { get; } = breed;
}
thanks this is great!

Looks like copy of the Kotlin language syntax.
🙂
Java + Kotlin = C#

[@antosha2224]

No its Kotlin is copy of C#. C# was created in 2001 and Kotlin was created only in 2016 after 15 years of C# exising

[@maneshwar3468]

@@antosha2224 Nope. C# introduced many new features in version 12, those features ex, primary constructor, look similar to Kotlin Lang.

[@antosha2224]

​@@maneshwar3468 So what? Originaly Kotlin was inpired by C# and other languages. Some features was copied directly from C# . Here is the text from their oficial documentation in kotlin org / introduction : "Kotlin took inspiration from many programming languages, including (but not limited to) Java, Scala, C# and Groovy. ". You can go to Kotlin docs intrudaction and read this by yourself. So creator of Kotlin by himself says that Kotlin was inpired by C# and you says "NOPE" lol
