        {
            var demoGroup = context.AddGroup("Group");

            // 由于通知的多样性, 需要使用模板消息来传递数据
            demoGroup.AddNotification("Faulted")
                .WithTemplate(template => { });
            demoGroup.AddNotification("Cancelled")
                .WithTemplate(template => { });
            demoGroup.AddNotification("Suspended")
                .WithTemplate(template => { });
            demoGroup.AddNotification("Completed")
                .WithTemplate(template => { });
        }
    }

```csharp

    // 定义工作流
    public class DemoWorkflow : IWorkflow
    {
        public void Build(IWorkflowBuilder builder)
        {

                .SetVariable("demo", context =>
                {
                    // 可传递自定义参数, 将作为瞬时变量写入到发布的通知数据中
                    context.WithNotificationData("demo", "demo");
                    // 自定义用于发布通知的租户标识
                    context.WithNotificationTenantId(Guid.NewGuid());
                })
                .WriteLine("Start a workflow.")
                .WriteLine("Workflow finished.");
