Use this API sample to validate a workflow.
IWorkflowEngine engine = WorkflowRuntime.Engine;
Workflow workflow = engine.GetService<IWorkflowDefinitionService>().GetWorkflow(workflowId);
ValidationContext validationContext = new ValidationContext(engine);
validationContext.Options.IsRecursive = true;
Validator validator = Validator.GetValidator(workflow, engine);
validator.Validate(validationContext);
foreach(ValidationError error in validationContext.Errors)
{
//do whatever you want with an error…
}
