install the SDK, that gets you the compiler and toolchain $vscode

MODiX•2y ago

1) Install the C# extension 2) 2.a) DO NOT USE OPEN FILE 2.b) Always use Open Folder (from the File menu), and open the folder containing your sln file (or the folder containing the csproj if you have only one csproj) 3) To make the extension start and detect C#, either: 3.a) wait for the prompt that will appear on the bottom right of your screen that ask you if you want it to create some files, and say Yes 3.b) Command Palette (F1 or Ctrl+Shift+P) and type > .Net : Generate Assets for build and run 4) you should see a flame on the Status bar with the Omnisharp logo (see second attached screenshot) 5) it should load to finally say OmniSharp server is running (if not ask for help) https://media.discordapp.net/attachments/569261465463160900/1006652191689429022/unknown.png https://cdn.discordapp.com/attachments/569261465463160900/951015732769079336/unknown.png

C# pretty much only has a single compiler, and that's the compiler that comes with the .NET SDK, linked above

thievedOP•2y ago

ohh i see im not familiar with these kinda concepts yet like .NET and stuff i come from languages where simplicity is a given lol

Thinker•2y ago

Are you familiar at all with Java?

thievedOP•2y ago

i can write basic programs in it i wanna learn C# and become a more in-depth programmer so i can understand concepts like multi-threading, single-threading, etc. i understand them at a surface level

jcotton42•2y ago

imagine Java, but the language and tooling aren't freeze dried dog vomit

thievedOP•2y ago

oh!

jcotton42•2y ago

thievedOP•2y ago

lol okay C# just looks really interesting to write in its used in so many things like FPS unlockers, viruses, web even etc.

Thinker•2y ago

You can think of .NET as the ecosystem (eg. tooling, compilers, languages) that surrounds C#.

thievedOP•2y ago

C# comes with libraries?

Thinker•2y ago

don't write viruses, you'll be banned from this server catsip

thievedOP•2y ago

like community libraries?

Thinker•2y ago

yeah

thievedOP•2y ago

oh i know any virusware by me is simply for demonstration to test on my VMs lol

Thinker•2y ago

Check out https://www.nuget.org where you'll find all the libraries under the sun

NuGet Gallery | Home

The NuGet Gallery is the central package repository for NuGet, the package manager for .NET.

thievedOP•2y ago

im not a blackhat programmer i had a question so C# has a community library right but things like C and C++ dont? ive always wondered lol ive never looked

jcotton42•2y ago

C/C++ do conan & vcpkg

thievedOP•2y ago

ohhhh i see

Thinker•2y ago

well "library" is an ambiguous term, usually it just refers to pieces of code written by others which you can use in your own code

thievedOP•2y ago

yea well what i really mean is your code can be assisted by other people's code like NPM, etc. a global repository of tools

Thinker•2y ago

Python and Lua also have libraries, ex. Numpy

thievedOP•2y ago

yea lua is an extension language so u have to install luvit or luarocks for community works (like actual requirable packages)

thievedOP•2y ago

got it

thievedOP•2y ago

just run?

Thinker•2y ago

looks like the installer yeah run that

thievedOP•2y ago

coolio

Thinker•2y ago

Also, I hope you're familiar with using the console for stuff, because using VSCode means that you'll have to use the console for a lot of stuff

thievedOP•2y ago

oh ofc im familiar with console commands windows or external lol i dont like visual studio because i dont feel like i have controlover my process visual studiocode is just an IDE really that consists of extensions

thievedOP•2y ago

thievedOP•2y ago

thievedOP•2y ago

what else is there to the toolchain ?

Thinker•2y ago

wdym? dotnet is pretty much all you need for most things

thievedOP•2y ago

ohh i sde see is nuget an extra installable ? like with rust you can install uhh cargo or whatever idk

Thinker•2y ago

dotnet build to build your projects dotnet run to run your projects dotnet publish to publish your projects dotnet add package to add Nuget packages dotnet test to run tests

thievedOP•2y ago

ohh so nuget isbuilt in

Thinker•2y ago

yep

thievedOP•2y ago

radical let me try it one sec im gonna learn C# by writing some bot code

Thinker•2y ago

There is a separate CLI for Nuget, although afaik that's only relevant for publishing packages Check out $helloworld if you need an introduction

sometimes i feel dumb because i dont know certain parts of tech-talk but theni realize i dont really need to if im solo programming lol ima try it out can i keep this open?

Thinker•2y ago

yeah sure

Aaron•2y ago

dotnet essentially has the same usage as cargo or npm

Thinker•2y ago

or like node + npm

thievedOP•2y ago

okay thats easy to understand good what do i run to start a new project? dotnet new ?

333fred•2y ago

Yup, that will show you the list of templates you can create

thievedOP•2y ago

got it! how do i know what kinda template i want though? i mean i know i need a console one but in what case should i need the ohter stuff lol

333fred•2y ago

Well, you'll look at the description

thievedOP•2y ago

hmm alright

Thinker•2y ago

You can start with dotnet new console That's just a regular console app

thievedOP•2y ago

yayyy

thievedOP•2y ago

namespace Epic
{
    public class Program
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Hi!");
        }
    }
}

namespace Epic
{
    public class Program
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Hi!");
        }
    }
}

awesome

Thinker•2y ago

btw, you can just write Console.WriteLine("Hi!"); if you want to skip the class and Main stuff

thievedOP•2y ago

ohhh whats the point of a namespace then?

Thinker•2y ago

namespaces are only really useful if you're dealing with multiple classes namespaces are like folders on your computer, they help you organize classes into categories

thievedOP•2y ago

ohhh so what if i just want one class?

Thinker•2y ago

Then you don't need a namespace, although it's kinda good practice to use one regardless (usually just the name of your app)

thievedOP•2y ago

oh i see sorry for asking all this i just know that it might not be easy to find specific thing slike this but if i wanted to require one class from a file without a namespace how would that work?

Thinker•2y ago

You just type its name

// File 'Foo.cs'
class Foo {}

// File 'Foo.cs'
class Foo {}

// File 'Program.cs'
Foo foo = new Foo();

// File 'Program.cs'
Foo foo = new Foo();

thievedOP•2y ago

i mean for requiring i figured it would be that way though thank you but yea how would i require it?

333fred•2y ago

What do you mean "require"?

Thinker•2y ago

You don't 'require' things in C# If Foo happens to be from another library, then you have to add a reference to that library, but otherwise you don't have to do anything C# operates on the existence of .csproj files, which act as the root of a single project. If you run dotnet new console -n "MyProject", it'll generate a MyProject.csproj in the root directory. All .cs files in the root directory or any sub-directories are part of the project, and all classes declared in those files can be used in any of the other files. So the classes are just 'required' automatically However, if you group your classes into namespaces (as you typically should), then you'll have to put using YourNamespace; at the top of your file(s) in order to use classes inside that namespace.

thievedOP•2y ago

using oh let me try

namespace Epic
{
    public class Program
    {
        public static void Main(string[] args)
        {
            Hi.Yell();
        }
    }
}

namespace Epic
{
    public class Program
    {
        public static void Main(string[] args)
        {
            Hi.Yell();
        }
    }
}

public class Hi
{
    public static void Yell()
    {
        Console.Write("HIIII!");
    }
}

public class Hi
{
    public static void Yell()
    {
        Console.Write("HIIII!");
    }
}

did it ! =D

333fred•2y ago

using does not mean what you are used to from JS Separate files are not separate scripts that need to be cross-linked

thievedOP•2y ago

i see so all classes unless specified in a namespace are globally referencable ? (unless its private)

333fred•2y ago

Barring other visibility things like private or internal, yes

thievedOP•2y ago

so what else is globally referencable ? any variable scenarios?

333fred•2y ago

There are no such things as global variables in C#

thievedOP•2y ago

i see

333fred•2y ago

Everything goes in a type

thievedOP•2y ago

so only classes are referencable across files?

333fred•2y ago

No. You can reference things off of classes You could say MyClass.MyStaticMethod(), for example

thievedOP•2y ago

yea like i did with Hi

333fred•2y ago

or myInstanceOfMyClass.MyInstanceMethod()

thievedOP•2y ago

well what i mean is i can use classes across files, but what else can i use (without stating it with using)

333fred•2y ago

Nothing

thievedOP•2y ago

ah i see

333fred•2y ago

Everything is in a class

thievedOP•2y ago

i sorta understand so do you have to put namespaces in their own folders? or can you have them in the same dir and put using [Namespace];

333fred•2y ago

Namespaces and files have no relation Many people choose to organize their files in a fashion that is related to the namespace

thievedOP•2y ago

can namespaces be used with using even if theyre in the same dir? or if theyre in different ones?

333fred•2y ago

I think you're still trying to relate this to files and require Throw it all away

thievedOP•2y ago

yea im just trying to understand

333fred•2y ago

Namespaces are a virtual "file-like" structure

thievedOP•2y ago

i see

333fred•2y ago

If you're not in a namespace, then you can't see anything in that namespace by default, and you need to bring that namespace into scope by specifying using Namespace;

thievedOP•2y ago

alright that makes sense

333fred•2y ago

This can even happen in the same file Because you can have multiple namespaces in a single file

Thinker•2y ago

(but generally don't do that)

thievedOP•2y ago

to me right now, namespaces seem like @thinker227 said just folders for classes or whatever theyre used for but folders regardless

MODiX•2y ago

Orannis#3333

sharplab.io (click here)

namespace A {
    class InA { }
}
namespace B {
    class InB {
        InA NotVisible;
    }
}

namespace A {
    class InA { }
}
namespace B {
    class InB {
        InA NotVisible;
    }
}

React with ❌ to remove this embed.

thievedOP•2y ago

mm so in that, how would you access InA

333fred•2y ago

They are, but they're virtual folders. They have nothing to do with where your actual files are located

thievedOP•2y ago

using A; underneath the namespace? ofc files and such just seem to be preference

Thinker•2y ago

technically yeah

333fred•2y ago

You have 3 options: 1. using A; at the top of the file. (preferred) 2. using A; inside the namespace B { declaration. (You may see code like this, as something like 40% of of users do it this way) 3. Fully qualify InA, by saying A.InA where it's used 3 is sometimes used when you want to use a single type from a namespace and don't want to generally make the all the things in the namespace visible locally But it's rarer

thievedOP•2y ago

ohhhokay

namespace A
{
    public class B
    {
        public static void C()
        {
            Console.WriteLine("Yes!");
        }
    }
}

namespace A
{
    public class B
    {
        public static void C()
        {
            Console.WriteLine("Yes!");
        }
    }
}

using A;

namespace Epic
{
    public class Program
    {
        public static void Main(string[] args)
        {
            A.B.C();
        }
    }
}

using A;

namespace Epic
{
    public class Program
    {
        public static void Main(string[] args)
        {
            A.B.C();
        }
    }
}

got it
