Weird exception in WCF server

Strange exception occurred, when I tried to call the action in my proxy class exception mes开发者_开发百科sage: The message could not be processed because the action 'http://testservice//reports/IReportService//Report' is invalid or unrecognized.

Is that a typo that you have a second set of double forward slashes after 'testservice'?

'http://testservice//reports/IReportService/Report'
