[System.InvalidOperationException] = {"Could not find service of type 'TrainingApprovalSiteWorkflow.ITrainingSiteCreationService' through the currently configured services. Consider adding the service to ExternalDataExchangeService."}
According to the book I had to add, this to web.config
<WorkflowService Assembly="TrainingApprovalSiteWorkFlow, Version=1.0.0.0, Culture=neutral, PublicKeyToken=ec95eb8ee603c598" Class="TrainingApprovalSiteWorkflow.TrainingSiteCreationService">
</WorkflowService>
However I am not sure if I did to the correct web.config there are so many I added to inetpub\80\web.config Is it there or some other web.config?
