ComClass in C#

Saranya B

Hello Everybody, How can we create a class using ComClass Template. First of all, I am not able to add the reference of Microsoft.Build.Tasks.V3.5 since it is not being listed out in the Add Reference dialog. So I browsed this dll and added the reference. Still my problem is not solved. I am getting the following error. 'Microsoft.Build.Tasks.Deployment.ManifestUtilities.ComClass' is not an attribute class I am not sure. Here is my code,

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Build.Tasks.Deployment.ManifestUtilities;

namespace COMArray
{
[ComClass(ComClass2.ClassId, ComClass2.InterfaceId, ComClass2.EventsId)]

public class ComClass2
{
    

    #region "COM GUIDs"
    // These GUIDs provide the COM identity for this class 
    // and its COM interfaces. If you change them, existing 
    // clients will no longer be able to access the class. 
    public const string ClassId = "83a8275f-9282-4257-ba62-afab6ed03beb";
    public const string InterfaceId = "e75a1569-f1aa-4bdc-8e39-ae5807ee5baa";
    public const string EventsId = "f966bdd3-9c5b-4ad9-8714-bc17d28f7e3a";
    #endregion

    // A creatable COM class must have a Public Sub New() 
    // with no parameters, otherwise, the class will not be 
    // registered in the COM registry and cannot be created 
    // via CreateObject. 
    public ComClass2()
        : base()
    {
    }

    private int \_test;
    public int test
    {
        get { return \_test; }
        set { \_test = value; }
    }

}
