✅ "Build failed. Fix the compilation errors and try again."

So I started C# just a week ago and I've been struggling with a weird error message whenever I do dotnet run in the console. Everything was going just fine as soon as I add the int[] correctAnswers = {2, 2, 1}; to the code. Even after I removed it, the error is still the same... I do have .NET version 8.0 and every needed extension installed so I don't really understand why it's popping out. I've been trying to seek the answer on YouTube or via ChatGPT but they both failed. I'd love some help. The code:

using System;
class Program {
    static void Main(string[] args) {
        Console.WriteLine("e");

        string[] pytania = {
            "1. Ile nóg ma pająk?",
            "2. Która planeta jest najbliżej Słońca?",
            "3. Stolica Polski to?"
        };

        string[,] odpowiedzi = {
            {"1. Sześć", "2. Osiem", "3. Cztery"},
            {"1. Wenus", "2. Merkury", "3. Mars"},
            {"1. Warszawa", "2. Wrocław", "3. Gdańsk"}
        };

        int[] correctAnswers = {2, 2, 1};
    }
}

using System;
class Program {
    static void Main(string[] args) {
        Console.WriteLine("e");

        string[] pytania = {
            "1. Ile nóg ma pająk?",
            "2. Która planeta jest najbliżej Słońca?",
            "3. Stolica Polski to?"
        };

        string[,] odpowiedzi = {
            {"1. Sześć", "2. Osiem", "3. Cztery"},
            {"1. Wenus", "2. Merkury", "3. Mars"},
            {"1. Warszawa", "2. Wrocław", "3. Gdańsk"}
        };

        int[] correctAnswers = {2, 2, 1};
    }
}

Works just fine for me:

Weird that it would just randomly break like that Do you have any other files in the project?

UKPLOP•3w ago

uh well obj folder bin folder but idk if you mean these

UKPLOP•3w ago

Angius•3w ago

Yeah, that seems just fine Huh Try deleting bin and obj, and run dotnet run again?

UKPLOP•3w ago

they just randomly keep getting back and when I remove obj it needs admin permission to remove it

Angius•3w ago

Sure, they are generated when the project builds Which is why they're safe to delete, they'll be regenerated anyway Can't you delete it with admin perms?
