code builds but hangs while running

code: https://paste.pythondiscord.com/KTVQ when i build it in release, everything works fine. but when i run in release, it just hangs and does nothing, even though all i'm doing is this:

class Program
{
    // ... <- nothing up here is run

    static void DisplayHelp()
    {
        string help = """
        This is a test help screen.

        What do you think?
        """.Trim();

        Console.WriteLine(help);
    }

    static void Main()
    {
        DisplayHelp();
    }
}

class Program
{
    // ... <- nothing up here is run

    static void DisplayHelp()
    {
        string help = """
        This is a test help screen.

        What do you think?
        """.Trim();

        Console.WriteLine(help);
    }

    static void Main()
    {
        DisplayHelp();
    }
}

how do stacks, lists, arrays, etc have a collection expression?

is it part of the compiler or is there a special function or attribute you can give code in order for it to work that way?

"Object reference not set to an instance of an object"

code: https://github.com/axololly/chess/tree/main/Board.cs#L1073 not sure why this is happening. i changed the Board from a class to a struct so it's no longer heap allocated (used in an engine, so these things matter) and now it's raising weird errors like this

✅ this error makes no sense

getting a null reference exception here:

static Evaluation eval = new();

static Evaluation eval = new();

and that traces to this:

mgTable[pc][sq] = mgValue[p] + GetMGTable(p)[sq];

mgTable[pc][sq] = mgValue[p] + GetMGTable(p)[sq];

and THAT traces to this:

static int[][] mgTable = new int[12][];

static int[][] mgTable = new int[12][];

am i dumb or is this just not how you construct an array like that?

✅ how do i publish my .NET project?

so i made this chess thingy (do check it out, i spent a month on it) and I want to publish it online so i can primarily use it in my other projects. how exactly do i go about this? i'm using vscode btw - vs runs like shit and doesn't correct my code properly. command line would be preferred.

✅ impossible error

so i'm using a Stack<Move> for my chess board's move history. it somehow managed to raise an out-of-bounds error with the line being directly correlated to this line:

moveHistory.Push(move); // Index was outside the bounds of the array.

moveHistory.Push(move); // Index was outside the bounds of the array.

i have zero fucking clue what this is caused by. here's the rest of my code: https://mystb.in/4b14af70b18dc60777 (line 225-250)

null check raising errors

i come from python and my first interpretation was that they can work like decorators, but that's clearly not the case. my question is how do i modify class data with an attribute? like how in python you can decorate a class like this:

def change(name, value):
    def wrapper(cls):
        setattr(cls, name, value)
        return cls

    return wrapper

# ...

@change("num", 4)
class MyClass:
    def __init__(self):
        self.num = 10

mc = MyClass()
print(mc.num) # prints 4 and not 10

def change(name, value):
    def wrapper(cls):
        setattr(cls, name, value)
        return cls

    return wrapper

# ...

@change("num", 4)
class MyClass:
    def __init__(self):
        self.num = 10

mc = MyClass()
print(mc.num) # prints 4 and not 10

how would i do this in C#?

✅ Inconsistent accessibility error - no idea where this came from

Full error:

                .ToArray();

✅ while loop on cpu

is there a type of while loop that doesn't hammer the cpu with checks? like when i type a character, THATS when it updates, instead of as many times as it possibly can, because it slows down my pc and i dont get these issues with other CLI tools (eg. python repl)

how do i rotate part of a multidimensional matrix?

i have a 2D matrix representing a rubik's cube (figured that a 3D matrix would be both quite difficult and a massive overhead) and i want to rotate just one of the inner 1D matrices to rotate just one face of the side. how would i do this?

✅ how do i override built-in methods?

i come from python where you can override methods in a class to work a certain way. for example, for use in the == operator, you can override a class to modify the behaviour of the __eq__ method which checks if two objects are equal. if i wanted to do an XOR on a class that holds an internal value, how can i override it so it works on the internal value instead of the class itself?
