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
