ASP.NET Core 6部署至IIS遇500错误：无匹配路由

问题现象 #

• 本地IIS Express（https://localhost）运行正常，部署到IIS后出现异常
• 采用框架依赖模式发布，已完成IIS必要配置（安装.NET托管包等步骤）
• 同事成功部署同版本应用，但使用其发布文件夹在本地IIS部署仍报错
• 代码断点（含Program.cs）未触发，除首页外其他页面显示空白，控制台报404错误
• 事件查看器及发布文件夹日志均抛出InvalidOperationException: No route matches the supplied values错误

根因定位 #

问题出在Program.cs的路由配置中
