Visual Studio代码调试默认ASP.NET核心MVC WebApp:无效

我创建项目时使用了: dotnet new mvc 在一个 Meow 文件夹,没有什么特别的,然后添加了一个新的配置 .NET Core Launch (web) .

事实证明,只有一个呼叫 dotnet build build 任务 tasks.json 定义见 preLaunchTask launch.json 这就是调试过程的开始和停止,没有显示任何错误。

跑步时 dotnet run ,一切正常,因此我怀疑问题更多地来自我的Visual Studio调试配置。

下面两个自动生成的文件看起来不错。
