ASP.NET Core双Profile的launchsettings.json配置失效问题求助

你的配置存在几个致命的结构错误，导致合并后无法启动：

• 错误将多个独立启动配置（比如TrainingAPP_API、https、IIS Express）嵌套在了Development和Production节点下，profiles对象下的每个节点必须是独立的启动Profile，不能互相嵌套。
• $schema和iisSettings是全局根层级配置，不该放到每个Profile内部。
• Production环境的ASPNETCORE_ENVIRONMENT错误设置为Development，违背了生产环境的配置意图。
• 硬编码executablePath完全没必要，commandName: "Project"类型的配置会自动识别程序集路径。

修复后的正确配置如下：

{
  "$schema": "https://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:56132/",
      "sslPort": 44328
    }
  },
  "profiles": {
    "Development": {
      "commandName": "Project",
      "dotnetRunMessage": true,
      "launchBrowser": true,
      "launchUrl": "swagger",
      "applicationUrl": "https://localhost:7001;http://localhost:5186",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "Development (HTTPS)": {
      "commandName": "Project",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "dotnetRunMessages": true,
      "applicationUrl": "https://localhost:7064;http://localhost:5050"
    },
    "Development (IIS Express)": {
      "commandName": "IISExpress",
      "workingDirectory": "C:\\Users\\jacob\\Desktop\\C#\\TrainingApp",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "Production": {
      "commandName": "Project",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Production"
      },
      "applicationUrl": "http://localhost:5050"
    },
    "Production (HTTPS)": {
      "commandName": "Project",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Production"
      },
      "dotnetRunMessages": true,
      "applicationUrl": "https://localhost:7064;http://localhost:5050"
    },
    "Production (IIS Express)": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Production"
      }
    }
  }
}

说明：

• 把原来嵌套的子配置都改成profiles下的独立Profile，并给每个Profile起清晰的名字，方便区分环境和启动方式。
• 全局配置$schema和iisSettings移到根节点。
• 修正Production环境的环境变量为Production。
• 去掉不必要的executablePath配置，让dotnet自动处理程序启动路径。
