ASP.NET CORE 5 MVC缺少除HOMECONTROLLER以外的所有控制器的默认操作

Question

我使用ASP.NET Core 5 MVC，并且有一个有趣的问题。当我想加载任何控制器的索引方法时，我也必须将索引动作名称写入URL。如果我只在URL中写入控制器名称，那么它就不会加载。我没有任何例外。我没有在root目录中使用名称与任何控制器名称匹配的文件夹。我使用默认路由，所以我不明白有什么问题。但是我在调​​试时注意到了一个有趣的东西。我尝试通过数据通知设置自定义路由路径。当我重命名控制器时，我会得到模棱两可的异常。

“模棱两可的matchException：请求匹配多个端点。 匹配：
