事件查看器

事件查看器有这两个错误

• Application ‘/LM/W3SVC/2/ROOT’ with physical root ‘C:\Users\Administrator\Desktop\ASP.NET Core\RazorPagesMovie’ has exited from Program.Main with exit code = ‘0’. Please check the stderr logs for more information.
• Application ‘/LM/W3SVC/2/ROOT’ with physical root ‘C:\Users\Administrator\Desktop\ASP.NET Core\RazorPagesMovie’ failed to load coreclr. Exception message:

  各种捣腾就是不行，看好多贴子都不行。
  最后安装asp.net core 3.1 ，之后再卸载，程序跑下就好了。可能有些东西没有安装好。
  下载安装：aspnetcore-runtime-3.1.16-win-x64
