Is there a good reason to write code in Program.cs/main as opposed to using classes? [closed]

Answer 1

You do know that the entry point of a console application is configurable, right?

My preferred method would be:

class MeaningfullyNamedProgram { 
    public static void Main(string[] args) {
        var program = new MeaningfullyNamedProgram(args);
        program.Run();
    }

    public MeaningfullyNamedProgram(string[] args) { 
    }

    public Run() {
        // well structured, broken-out code follows 
    }
}

Point the entry point of the project at MeaningfullyNamedProgram.Main

NOTE: I'll leave it as an exercise for the reader, but you could create a base class for this using generics, and save yourself some typing.
