    I have generated WCF Data Service from OpenAccess Service Wizard and I can browse http://localhost:15241/EntitiesModelService.svc when I run the project under VS2012.

    When I deploy to the remote IIS server, I can't browse to it and it gave me the following error:

    Exception information:
        Exception type: InvalidOperationException
        Exception message: The type 'WCFDataService.EntitiesModelService', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found.
       at System.ServiceModel.Activation.ServiceHostFactory.CreateServiceHost(String constructorString, Uri[] baseAddresses)
       at System.ServiceModel.ServiceHostingEnvironment.HostingManager.CreateService(String normalizedVirtualPath, EventTraceActivity eventTraceActivity)
       at System.ServiceModel.ServiceHostingEnvironment.HostingManager.ActivateService(ServiceActivationInfo serviceActivationInfo, EventTraceActivity eventTraceActivity)
       at System.ServiceModel.ServiceHostingEnvironment.HostingManager.EnsureServiceAvailable(String normalizedVirtualPath, EventTraceActivity eventTraceActivity)

    My Web.config:
    <?xml version="1.0"?>

    Hello JiFong,

    Since the WCF project is working fine in Visual Studio there should be an issue with the deployment process. Particularly this error might occur if the assembly of your WCF project is not deployed to the bin folder where the application is deployed. Please make sure that all the required assemblies are located in the bin folder of the deployment directory.

    If the suggested resolution doesn't help in your scenario or if something else is causing exceptions do not hesitate to contact us again for assistance.
