i write an add-on for internet explorer 11

i am already add guid variables

[ComVisible(true), Guid("86524891-49EB-4F46-BAE3-C5545B81A671"), ClassInterface(ClassInterfaceType.None)]

and already add referances MSHTML and SHDocVw and already write ComRegister function, unregister function

[ComRegisterFunction]
   public static void RegisterBHO(Type type)
   {
       RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(BHOKEYNAME, true);

       if (registryKey == null)
       {
           registryKey = Registry.LocalMachine.CreateSubKey(BHOKEYNAME);
       }
       string guid = type.GUID.ToString("B");
       RegistryKey ourKey = registryKey.OpenSubKey(guid);
       if (ourKey == null)
       {
           ourKey = registryKey.CreateSubKey(guid);
       }
       ourKey.SetValue("Alright", 1);
       registryKey.Close();
       ourKey.Close();
   }
[ComUnregisterFunction]
   public static void UnregisterBHO(Type type)
   {
       RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(BHOKEYNAME, true);
       string guid = type.GUID.ToString("B");

       if (registryKey != null)
       {
           registryKey.DeleteSubKey(guid, false);
       }
   }

and already write set / getsite functions

public int SetSite([MarshalAs(UnmanagedType.IUnknown)] object site)
        {
        if (site != null)
        {
            webBrowser = (SHDocVw.WebBrowser)site;
            webBrowser.DocumentComplete += new DWebBrowserEvents2_DocumentCompleteEventHandler(this.OnDocumentComplete);
            webBrowser.BeforeNavigate2 += new DWebBrowserEvents2_BeforeNavigate2EventHandler(this.OnBeforeNavigate2);
            webBrowser.NavigateComplete2 += WebBrowser_NavigateComplete2;
        }
        else
        {
            webBrowser.DocumentComplete -= new DWebBrowserEvents2_DocumentCompleteEventHandler(this.OnDocumentComplete);
            webBrowser.BeforeNavigate2 -= new DWebBrowserEvents2_BeforeNavigate2EventHandler(this.OnBeforeNavigate2);
            webBrowser.NavigateComplete2 -= WebBrowser_NavigateComplete2;
            webBrowser = null;
        }
        return 0;
    }
    private void WebBrowser_NavigateComplete2(object pDisp, ref object URL)
    {

    }
    public int GetSite(ref Guid guid, out IntPtr ppvSite)
        {
        IntPtr punk = Marshal.GetIUnknownForObject(webBrowser);
        int hr = Marshal.QueryInterface(punk, ref guid, out ppvSite);
        Marshal.Release(punk);
        return hr;
    }
