异常如下
【尝试一】
百度搜索cc7b13ffcd2ddd51找到类似情况
https://learningintheopen.org/tag/publickeytokencc7b13ffcd2ddd51/
重新下载安装最新的.Net Framework
问题并没有解决
仔细一看我和上面这个博客的问题不一样！！！
我复制了异常的详细信息如下：
异常提示我找不到System.Configuration.configurationManager这个程序集，但是我的SDK里面明明有这个包。
【尝试二】
但是.NETCore的版本只有2.1比官网最新的2.2要旧，所以我想重装.NET core试试
结果还是不行
【尝试三】
打开手动找到system.configuration的dll文件并加入引用
结果还是不行！！！
最后！！！！！！
我看到了这段话
原来我最初创建的项目类型就出了问题。
应该创建这个.NET Framework控制台应用
