修改 launchSettings 后出错：无法应用启动配置文件“（默认）”

Question

我正在将我的项目设置为使用 dotnet watch 在 Visual Studio 2019 Preview 16.9.0 下的 launchSettings.json 中运行

下面是我的launchSettings.json

{
  "profiles": {
    "MyWebsite": {
      "commandName": "Executable",
      "executablePath": "dotnet",
      "commandLineArgs": "watch run",
      "workingDirectory": "$(ProjectDir)",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "dotnetRunMessages": "true",
      "applicationUrl": "https://localhost:5001;http://localhost:5000"
    }
  }
}

这是我点击时的输出CTRL+F5

watch : Started
The launch profile "(Default)" could not be applied.
A usable launch profile could not be located.
[17:38:49 INF] Starting up
[17:38:49 INF] User profile is available. Using 'C:\Users\MyUser\AppData\Local\ASP.NET\DataProtection-Keys' as key repository and Windows DPAPI to encrypt keys at rest.
[17:38:50 INF] Now listening on: http://localhost:5000
[17:38:50 INF] Now listening on: https://localhost:5001
[17:38:50 INF] Application started. Press Ctrl+C to shut down.
[17:38:50 INF] Hosting environment: Development
[17:38:50 INF] Content root path: C:\dev\MyWebsite\src\MyWebsite

我不明白为什么我会收到此消息：

The launch profile "(Default)" could not be applied.
A usable launch profile could not be located.

根据此解决方案/sf/answers/4596649291/，这是不应该发生的。

如何解决此消息？

只是改变

"MyWebsite": { "commandName": "可执行文件",

到

"我的网站": { "commandName": "项目",
