2. present context

I have been using Preview1 - Preview6 (currently the latest 2024/5/1). In the first version, I used it to put it into one of my microservices (https://gitee.com/SkyNingDuan/PublicActivityServices.git) and kept updating it iteratively.

在其中，我一直使用外部 RabbitMQ 的方式给我的微服务传递消息（用的是Zack.EventBus），但是它一直有直接通过 Aspire 方式创建 RabbitMQ 容器在你的项目中使用, 我一直想着用杨中科老师的框架为指导，开发一个在 Aspire 环境下的 EventBus, 但是一直拖着（已经有现成的了，就一直不想走出舒适区）最后经过不断的自我抗争，simpleUseAspireRabbitmq 第一版开发好了，功能比较简单，也比较好用，如果大家热情高的话, 后面再加便是。欢迎大家拥抱新技术，有任何问题都可以提 issue 和我互动，源代码地址https://github.com/skyDuanXianBing/SimpleUseAspireRabbitMQ.git ，NuGet 名称：SimpleUseAspireRabbitMQ) （目前由于 Aspire 也是处于预览版，所以这个也是预览版，后面有任何改进也会跟进的）。

3. usage tutorial

3.1. Creating the Aspire Project

在 aspire.host 中安装Aspire.Hosting.RabbitMQ 包，在program.cs中创建RabbitMQ容器，并且在你要使用 RabbitMQ 的项目后 WithReference RabbitMQ容器：

3.2. Registration service

在你要使用RabbitMQ项目的 program.cs 中分别加入builder.EventConfiguration("rabbitmq", "myexchange");（第一个参数是RabbitMQ容器名称，第二是交换机名称)，app.RegisterRabbitmqEvent();来注册服务：
