次のエラーが表示されます。

The type 'Drive_Service.DriveSessionsController', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found. 

サービス名と名前空間が同じでない場合にこれがスローされる可能性があることは理解していますが、おそらく50回以上チェックしましたが、同じように見えます。なぜこのエラーが発生するのかわかりません。
