Microsoft.Office.Interop.Outlook.MailItem does not contain a definition for Sender...?

I am trying to use the following code sample from msdn:

private string GetSenderSMTPAddress(Outlook.MailItem mail)
{
    string PR_SMTP_ADDRESS = @"http://schemas.microsoft.com/mapi/proptag/0x39FE001E";
    if (mail == null)
    {
        throw new ArgumentNullException();
    }
    if (mail.SenderEmailType == "EX")
    {
        //This rows gives an error:
        //Microsoft.Office.Interop.Outlook.MailItem does not contain a definition for Sender
        Outlook.AddressEntry sender = mail.Sender; 
        if (sender != null)
        {
            //Now we have an AddressEntry representing the Sender
            if (sender.AddressEntryUserType == Outlook.OlAddressEntryUserType.olExchangeUserAddressEntry ||
                sender.AddressEntryUserType == Outlook.OlAddressEntryUserType.olExchangeRemoteUserAddressEntry)
            {
                //Use the ExchangeUser object PrimarySMTPAddress
                Outlook.ExchangeUser exchUser = sender.GetExchangeUser();
                return (exchUser != null) ? exchUser.PrimarySmtpAddress : null;
            }
            return sender.PropertyAccessor.GetProperty(PR_SMTP_ADDRESS) as string;
        }
        return null;
    }
    return mail.SenderEmailAddress;
}

But for some reason I'm getting this compile error:

'Microsoft.Office.Interop.Outlook.MailItem' does not contain a definition for 'Sender' 
and no extension method 'Sender' accepting a first argument of type 
'Microsoft.Office.Interop.Outlook.MailItem' could be found 
(are you missing a using directive or an assembly reference?)

I'm using winforms with framework 3.5, wat can I do...?

See HowTo: Convert Exchange-based email address into SMTP email address . It supports earlier Outlook versions.

P.S. You may check the Outlook interop reference by choosing it in the Solutions Explorer window. In the Properties window will find its version.
