Program does not contain a static 'Main' method suitable for an entry point

[PaperPrototype]

it worked, then it didn't. So I deleted everything and cloned again... same error

Changing the code to this does work though

using System;

class Program
{
    static void Main(string[] args)
    {
        // Your program logic goes here
        Console.WriteLine("Hello from the static Main method!");

        // Example of using command-line arguments
        if (args.Length > 0)
        {
            Console.WriteLine($"First argument: {args[0]}");
        }
    }
}

PS: You've got intellisense working?! This is awesome dude, I've definitely gotta figure out how you did that

Oh, so it seems to work but only after you've ran some other code successfully. That's weird...

I've seen this a couple of times myself actually - I think its a race condition somewhere, but I've not really spent any time looking inot it.
