• Software Development for Windows Vista How to prevent an Workflowinstance from terminating

  Hi there I'm currently working on a (runtime-)service that should start a workflow for errorhandling if an instance faults. The service works fine as long as I trigger it by the instance's terminate event (Runtime -> WorkflowTerminated), but I want to prevent  the instance from terminating and instead suspend it so it could be resumed and starts at the State that caused an error previously.
