Creating Add-in for C#

I have not sent the correct code, it does not even compile. Here's the code is compiled. But this is C #, not VB. And you sent a sample solution to the problem VB.

Below is the code with the implementation of the interface IEdmAddin5 in the language C #.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using EdmLib;

namespace SetInventarNumber_library

{

    public class SetSerNo : IEdmAddIn5

    {

        public void GetAddInInfo(ref EdmAddInInfo poInfo, IEdmVault5 poVault, IEdmCmdMgr5 poCmdMgr)

        {

            poInfo.mbsAddInName = "My first add-in";

            poInfo.mbsCompany = "SPC-ALMAZ-FAZOTRON";

            poInfo.mbsDescription = "This is a very nice add-in.";

            poInfo.mlAddInVersion = 1;

            poInfo.mlRequiredVersionMajor = 5;

            poInfo.mlRequiredVersionMinor = 2;

            poCmdMgr.AddCmd(1, "My first menu command");

        }

        public void OnCmd(ref EdmCmd poCmd, ref Array ppoData)

        {

            EdmVault5 Vault;

            Vault = (EdmVault5)poCmd.mpoVault;

            Vault.MsgBox(poCmd.mlParentWnd, "Hello World!");

            string str = UpSreNo(Vault);

            Vault.MsgBox(poCmd.mlParentWnd, str);

        }

        //************************************************************************************************//

        private string UpSreNo(EdmVault5 Vault)

        {

            IEdmSerNoGen6 Generator = Vault.CreateUtility(EdmUtility.EdmUtil_SerNoGen);

            string next_number = Generator.GenerateSerNo("Инвентарный номер подлинника");

            return next_number;

        }

    }

}

In the first image, all as it should

and that's what is shown in the second image is not in the C # project.

The project compiles without errors. The result is a file SetInventarNumber_library.dll. But when you add the file to the administrative tool, there is the same error as before.

Could you please provide links to these templates on the site solidworks.com.

But then there was the next problem.: Dll file is added, and in the context menu command is added "My first menu command", but when I call the command, nothing happens. Although the actions have to be generated in the method OnCMD:

public void OnCmd(ref EdmCmd poCmd, ref Array ppoData)

        {

            EdmVault5 Vault = new EdmVault5();

            Vault = (EdmVault5)poCmd.mpoVault;

            Vault.MsgBox(poCmd.mlParentWnd, "Hello World!");

        }

Or something I did not understand?
