                        {
                            throw new Exception(string.Format("Config key:{0} was expected to be of type {1} but was not.", key, expectedType), ex);
                        }
                }

推荐答案

将文本输入光标放在"IConfiguration"一词中. 看一下单词的左手边. "I"下方将有一个空心的蓝色小条.
将鼠标悬停在该栏上，将出现一个下拉列表.打开下拉菜单，然后查看选项.
如果它们仅由"Generate Class"和"Generate Type"组成，则需要添加对包含IConfiguration的程序集的引用.
如果那里还有其他任何东西，那么使用它应该可以解决您的问题.

Place your text entry cursor in the word "IConfiguration".
Look at the left hand end of the word. There will be a small hollow blue bar under the "I".
Hover the mouse over this bar, and a dropdown will appear. Open the dropdown and look at the options.
If they consist of just "Generate Class" and "Generate Type" they you need to add a reference to the assembly containing IConfiguration.
If there is anything else there, then using that should solve your problem.
