WCF service method as WF activity RRS feed

  • Question

  • I am trying to use WCF service method in Windows Workflow. It was working fine before but all of sudden getting the following error:

    The activity 'Send' with OperationName='GetTaskById' must specify either the Endpoint or EndpointConfigurationName property.

    Added WCF service reference in WF project library

    <binding name="BasicHttpBinding_ITaskService" />
    <endpoint address="http://localhost:59137/Tasks.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ITaskService" contract="TasksService.ITaskService" name="BasicHttpBinding_ITaskService" />

  • Hi caxfax,

    Welcome to workflow forum.

    According to the your description above, you want to use WCF service in workflow. First it's recommended to check how to configuring bindings for Windows Communication Foundation Services here.

    In addition, you can consume a WCF service from a Workflow where both the service and the workflow live in the same web site.  See: How to consume a WCF Service from a WF4 Workflow 

    Please let me know if there is anything that I can do to help.

    Best regards,

  • Caxfax,

    You indicate that the workflow was successfully sending the WCF service requests.

    Did you rebuild anything? Did the service change such that the workflow would need to have its service reference changed? How did you add the activities to your workflow after you added the service reference?
