How to fix CS1729 error in this CAD application?

Question

Good morning, I have a problem in a CAD application where it shows the following error:

CS1729 error: "Commandmethodattribute" does not contain a constructor that accepts 0 arguments

1- AUTODESK.AUTOCAD.RUNTIME

    using System;

namespace Autodesk.AutoCAD.Runtime
{
    [AttributeUsage(AttributeTargets.Method, AllowMultiple = true, Inherited = false)]
    public sealed class CommandMethodAttribute : Attribute, ICommandLineCallable
    {
        public CommandMethodAttribute(string globalName);
        public CommandMethodAttribute(string globalName, CommandFlags flags);
        public CommandMethodAttribute(string groupName, string globalName, CommandFlags flags);
        public CommandMethodAttribute(string groupName, string globalName, string localizedNameId, CommandFlags flags);
        public CommandMethodAttribute(string groupName, string globalName, string localizedNameId, CommandFlags flags, Type contextMenuExtensionType);
        public CommandMethodAttribute(string groupName, string globalName, string localizedNameId, CommandFlags flags, string helpTopic);
        public CommandMethodAttribute(string groupName, string globalName, string localizedNameId, CommandFlags flags, Type contextMenuExtensionType, string helpFileName, string helpTopic);

        public virtual string HelpTopic { get; }
        public virtual string HelpFileName { get; }
        public virtual Type ContextMenuExtensionType { get; }
        public virtual CommandFlags Flags { get; }
        public virtual string GroupName { get; }
        public virtual string LocalizedNameId { get; }
        public virtual string GlobalName { get; }
    }
}

2 - MYCOMMANDS

using Autodesk.AutoCAD.Runtime;
using Linq2Autocad;

namespace Posteamento
{
    public class MyCommands
    {
        [CommandMethod] // Aqui ocorre o erro.
        public void Esforcos()
    {
      using (AcadDatabase acadDatabase = AcadDatabase.DoDocumentoAtual())
      {
        try
        {
          new Rede(Escolhe.Polyline("\nEscolha a rede"), (IDesenha) acadDatabase.Desenhador()).InsereEsforcos(6);
        }
        catch
        {
        }
      }
    }

        [CommandMethod]// Aqui ocorre o erro.
    public void EsforcosSem()
    {
      using (AcadDatabase acadDatabase = AcadDatabase.DoDocumentoAtual())
      {
        try
        {
          new Rede(Escolhe.Polyline("\nEscolha a rede"), (IDesenha) acadDatabase.Desenhador()).InsereEsforcos();
        }
        catch
        {
        }
      }
    }

        [CommandMethod]// Aqui ocorre o erro.
    public void InsereChamada()
    {
      using (AcadDatabase acadDatabase = AcadDatabase.DoDocumentoAtual())
      {
        try
        {
          new Rede(Escolhe.Polyline("\nEscolha a rede"), (IDesenha) acadDatabase.Desenhador()).InsereChamada();
        }
        catch
        {
        }
      }
    }
  }
}

PS: I’m not in the area of computer science, I’m a designer and this application calculates the results of efforts between poles of an electrical network. I want to change because currently it performs the calculations with cables of 35mm² and need to change to another cable in order to expedite the service in the office. I do not know if only with this information it would be possible to know how to correct the error.

Thank you very much!
