Visual Studio ASP.NET 核心调试 IIS Express - 无法访问站点

Visual Studio ASP.NET Core Debug IIS Express - Site can't be reached

我一直在 Windows 10 PC 上开发 VS 2019 中的 ASP.NET Core 2.1 Web 应用程序。一切正常,在 Chrome/IIS Express 中调试没有问题。

我将我的项目复制到我刚开始使用的新 Win 10 计算机上。

当我尝试在 Chrome 中使用 IIS Express 调试项目时,我收到一个错误页面:无法访问此站点。

我遵循了 Overflow 文章中的各种建议修复方法,但似乎没有任何效果。这让我发疯,浪费了很多时间。我已经尝试了所有这些步骤,但没有成功:

launchSettings.json 文件

launchSettings.json
{
  "iisSettings": {
    "windowsAuthentication": true,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "https://localhost:44301/",
      "sslPort": 44376
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "CanvasWeb": {
      "commandName": "Project",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "applicationUrl": "http://localhost:61900/"
    }
  }
}

更新

我尝试了以下操作但仍未解决问题:

问题可能是 IIS Express 的 HTTPS 错误。 检查它: 创建一个没有 Https 的新 ASP.NET 核心 Web 应用程序。 在 Web 应用程序模板中取消选中/取消选择为 https 配置 Uncheck configure for https

如果新的 Web 应用程序运行,则为 IIS Express HTTPS 问题。 运行 流动的力量 shell 管理员 previliadge 代码将解决 IIS Express 问题。

我确实遇到了这个问题,并在互联网上进行了一些研究,但是找不到解决方案。然后,我决定关闭我的防病毒软件 (Kaspersky Internet Security 21.2) 并检查它是否能解决问题,之后一切都开始工作了!不幸的是,我找不到负责网络 activity 的防病毒设置,所以即使现在,如果我在 .NET 中测试后端 API,我也必须关闭防病毒一段时间((
