这段时间学习一个整洁架构的开源项目，这是一名澳大利亚的软件架构师在github上面分享的项目：https://github.com/jasontaylordev/CleanArchitecture
作者的架构根底扎实，而且能灵活运用各种最新最简洁的技术知识，这个项目就用到非常多，我把代码pull下来之后发现直接编译过程中出了不少错误，花了两天时间都解决了。其中很大一部分是关于前端项目的内容，作者直接使用MSBuild来完成打包和创建，这只是我第一次看到。
另外还通过NSwag.MSBuild完成Open API代码的生成和typescript代码生成（运用于Angular），其中一个让我很惊讶的是：他居然在项目编译的时候初始化了数据库，弄得我云里雾里。我修改连接字符串，从报错信息才知道是执行这部分脚本的时候，MSWage的内核里初始化了Core的项目，调用到了初始化数据库代码：
Executing file 'config.nswag' with variables 'Configuration=Debug'...
C:\Users\csuma.nuget\packages\nswag.msbuild\14.0.7\tools\Net80
下面是报错信息：
