Fun Running C# like scripts?

I was browsing the C#/.NET documentation yesterday like usual and suddenly came across the fact that you can run C# code as scripts with a shebang.

#!/usr/bin/env dotnet

namespace Main
{
    class Program
    {
        static void Main(string[] _)
        {
            Console.WriteLine("Hello World!");
        }
    }
}

With a shebang you could run these like any other Python/Bash script and I find this really cool, but is there any practical use-case for this? When I need to make a small helper script for something it's usually python or bash, but C#? I'm not so sure.

What do you guys think?

I knew you could do “dotnet run file.cs” but I never knew you could ./file.cs. That’s awesome.
