How to create a DLL using Visual Studio C# that registers with regsvr32 NOT regasm ?

Hi,
I'm trying to create a DLL to use in an application that is not .net.  (Actually Microsoft Dynamics Nav not that it should matter)

Anyways I created a class library and compiled to dll.  However I can only register it using regasm /tlb option.  This in return always gives me the Entry Point not found in the other application.  So my feeling is that I need to build some interface or something on top ?
public class TestDLL

    {

        private string myString = "EMPTY";
 

        public Tenging()

        {

        }
 

        public string MyProperty

        {

            get

            {

                return myString;

            }

            set

            {

                myString = MyProperty;

            }

        }

    }

you don't have the choice to use regasm.

First off the code snipped is wrong in the way that the constructor should of course be of TestDLL().

Anyways I don't understand what you mean by that !  Right now my only choice seems to be regasm but the result is not what I expect as when I try and use the DLL I always get the DLL Entry Point not found error.

Upon further reading I'm starting to think that I need to write some sort of COM wrapper or Interop.

Does anyone have a link to a good sample ?

Perhaps I'm not explaining the problem correctly.

What I want to accomplish is making a "old school" COM DLL using c#.net.  I can make a DLL that publishes its interface to .Net but not Win32.

I tried making a simple Class library using the ComClass in VB.net but that gave me the same result.  The Inteface (methods, attributes etc) is not published so when I open the DLL in a program like DLL Export Viewer it comes up empty.

Got it to work

Application->Assembly Information->Check Make Assembly COM-Visible
Build->Settings->Check Register for COM Interop
Signing->Check Sign the Assembly
using System.Runtime.InteropServices;
 

[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]

public interface ITestDLL

{

    [DispId(1)]

    string MyProperty {get; set; }

}
 

[ClassInterface(ClassInterfaceType.None)]

[ProgId("<Namespace>.TestDLL")]

public class TestDLL : ITestDLL

{

    etc.
