I am getting the following errors and warnings in my code and I am not sure as to why

I am using Microsoft Visual Studios, C#, and .NET. This is my code

using System.IO;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.Runtime;

[CommandMethod("OpenDrawing", CommandFlags.Session)]

 public static void OpenDrawing()
{
    string strFileName = "C:\\DRAFT.dwg";
    DocumentCollection acDocMgr = Application.DocumentManager;

    if (File.Exists(strFileName))
        {
            acDocMgr.Open(strFileName, false);
        }
        else
        {
            acDocMgr.MdiActiveDocument.Editor.WriteMessage("File " + strFileName +
                                                            " does not exist.");
        }
    }

When I try to run my code I get an error for public that says "CS0106: The modifier 'public' is not valid for this item. I also get a warning for OpenDrawing that says "CS8321: The local function 'OpenDrawing' is declared but never used.

I am pretty new to using C#, so any feedback would be helpful. Thank you!

The method is written as a top-level statement. The methods documentation says this:

In an application that uses top-level statements, the Main method is generated by the compiler and contains all top-level statements.

This means that OpenDrawing is effectively a local function within the compiler-generated Main method. This causes an error because local functions can't have access modifiers.

This can be fixed by placing the method in a class (and preferably a namespace):

namespace MyNamespace
{
    public class MyClass
    {
        // your OpenDrawing declaration here
    }
}

It can then be called as MyClass.OpenDrawing. This class should be kept in its own file with the same name as the class (i.e. MyClass.cs in the example) to keep the code organized.
