wpf的轻量级框架Stylet怎么做主线程的消息通知机制，可以参考Stylet的wiki文档，Home · canton7/Stylet Wiki · GitHub

也可以直接利用token进行针对下发。代码在下面

定义的Token：

    public static class ViewModelTokens
    {
        public static string WaitingViewModel = "ECCP.ViewModels.WaitingViewModel";

        public static string StrategyViewModel = "ECCP.ViewModels.LightingStrategyViewModel";
        public static string MasterStrategyViewModel = "ECCP.ViewModels.MasterStrategyViewModel";
       
        public static string MasterSettingViewModel = "ECCP.ViewModels.MasterSettingViewModel";//MasterControlViewModel
        public static string MasterControlViewModel = "ECCP.ViewModels.MasterControlViewModel";
    }

订阅事件：

//继承 IHandle
 public class LightingStrategyViewModel : ViewModelBase, IHandle<Dictionary<string, object>>
    {
        public LightingStrategyViewModel(IWindowManager windowManger, IEventAggregator eventAggregator
           )
        {
            WindowManger = windowManger;
            EventAggregator = eventAggregator;
//这里订阅
            EventAggregator.Subscribe(this, ViewModelTokens.StrategyViewModel);
           

        }
}

发布消息：

         //Stylet的IEventAggregator
  Stylet.IEventAggregator mediator = _serviceProvider.GetService<IEventAggregator>();
                Dictionary<string, object> keyValues = new Dictionary<string, object>();
                keyValues.Add("Id", hisModel.CommandKey);
                keyValues.Add("OnOrOff", openLighet);
                keyValues.Add("Brightness", brightness);
//根据token发布消息
                mediator.Publish(keyValues, ViewModelTokens.StrategyViewModel);

就这样
