What is the difference between Class and Code File in ASP.NET Core?

The "Class" option generates a C # code file with a basic class structure, like this:

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApp1
{
    class Class1
    {
    }
}

"Code File" generates an empty source code file, where you have to write everything from scratch. In practice the only difference is the template used in the first one.
