my problem service not start when right click on service1(on window services on windows 7) , click start.

i've found problem. changed onstart method.

protected override void onstart(string[] args) {     if (myservicehost != null)     {         myservicehost.close();     }     myservicehost = new servicehost(typeof(sendmailservice));     myservicehost.open();      wcfsendmail.sendmailservicewcf s = new wcfsendmail.sendmailservicewcf();     s.runprogram(); } 

and publish windows service project , run setup.exe in publish folder. of course using command installutil windowsservicesendmail.exe register on windows 7.
