两个源如何从两个源（视图）和其他模块并行交互

我有一个硬件模块，可以通过用户和另一个模块从View进行交互 .

Question:

我应该在MyModule_A中创建一个单例实例，将此实例注册到我的容器中并使用此容器来解析MyModule_B中的实例吗？

Or

我必须在两个模块之间使用Eventaggregator进行两次通信吗？

在这种情况下，棱镜文档对我来说并不清楚 .

• 解决方案指挥 . 在期望用户交互立即采取行动时使用 .

• 地区背景 . 使用此选项可在主机区域中的主机和视图之间提供上下文信息 . 这种方法有点类似于DataContext，但它不依赖于它 .

• 共享服务 . 呼叫者可以在服务上调用一种方法，该方法将事件引发给消息的接收者 . 如果以上都不适用，请使用此选项 .

• 事件聚合 . 用于在没有直接的动作反应期望的情况下跨视图模型，演示者或控制器进行通信 .
