简介
关于这个框架的背景，在前面我已经交代过了。不清楚的可以查看这个链接 极简实用的Asp.NetCore模块化框架决定免费开源了
在最近一段时间内，对这个框架新增了以下功能：
1、新增了CMS模块，目前整体都比较简单，适合个人博客使用。
2、新增了AOP缓存，使用AspectCore,缓存可做到Memarycache和redis一件切换。
3、新增AOP事务，服务层和控制器都可以打上特性标签使用。
4、对多租户使用Filter，不管是添加还是更新、查询即可自动赋值。
5、新增七牛云图片上传功能。
6、对于单表的增删改查，在控制器内做了封装，有新的业务按约定建立对应的CRUD实体，一套API自动完成。
7、后台管理新增站群管理。
说了那么多，让我们上点代码和截图来瞧一瞧吧。

总结
好了，又要到说再见的时候了，框架我只要有时间就会一直更新下去，不合理的地方欢迎浏览代码指导批评，我希望这个框架从简单的一点一滴做起，慢慢地把它做大做强。算是程序员阶段最后一次做框架了，什么时候不更新了，有可能就转行了。大家也可以不使用这个框架，只要里面地思路能帮助到一部分人，我认为这就足够了。
