❔ How does the main method work?

I've only ever used c# in unity, so i've never worked outside the context of making games, so using the main method is very new to me. Since the main method needs to be static anything i use in it requires being static. How do you navigate around this?

class Program
{
  static void Main() => new Program().Run();
  private void Run()
  {
    // code here...
  }
}

class Program
{
  static void Main() => new Program().Run();
  private void Run()
  {
    // code here...
  }
}

is generally the simplest way to get out of the static context your code starts in it's certainly what I do, with the new top level statement you can also do

// Startup.cs
new Program().Run():

// Startup.cs
new Program().Run():

then

// Program.cs
class Program
{
  public void Run() { /* ... */ }
}

// Program.cs
class Program
{
  public void Run() { /* ... */ }
}

you can still create instances of types and call their non-static methods

in addition to what the generic host does, there is also ConsoleAppFramework which adds some argument parsing the execute commands (similar to controllers in asp.net mvc) https://github.com/Cysharp/ConsoleAppFramework

large scale apps generally end up looking something like this...

public static void Main()
{
    using var myApp = new Application()
    {
        // settings and configuration
    };

    myApp.Run();
}

public static void Main()
{
    using var myApp = new Application()
    {
        // settings and configuration
    };

    myApp.Run();
}
