We have a website which we have re-designed and coded to work using System.Net.Mail but other parts of our website use System.Web.Mail We have specified the namespaces to be used in our web.config file but as we are specifying both System.Net.Mail and System.Web.Mail and they both use MailMessage it throws an error 'MailMessage' is ambiguous, imported from the namespaces or types 'System.Web.Mail, System.Net.Mail'. Is there anyway to avoid this error and still use both namespaces?
