I've WCF service hosted in console exe, then created clients in c# - all works ok.
When I trieed to sedn soap message from SOAPGUI I've received

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing">

         <s:Reason>
            <s:Text xml:lang="ru-RU">The message could not be processed. 
            This is most likely because the action 
            'http://tempuri.org/ImyDataAccessService/Connect' is i
            ncorrect or because the message contains an invalid or 
            expired security context token or because there is a mismatch between bindings. 
            The security context token would be invalid if the service 
            aborted the channel due to inactivity. 
            To prevent the service from aborting idle sessions prematurely increase 
            the Receive timeout on the service endpoint's binding.</s:Text>
