1、先安装.net framework4.0
2、再安装vc_redist.x64
vc_redist.x64下载地址： https://www.microsoft.com/zh-cn/download/confirmation.aspx?id=48145
3、在安装.NET Core SDK 和 .NET Core Runtime
4、如果浏览网站还是提示错误
HTTP Error 500.31 - Failed to load ASP.NET Core runtime Common solutions to this issue: The specified version of Microsoft.NetCore.App or Microsoft.AspNetCore.App was not found. Specific error detected by ANCM: Failed to load the dll from [C:\Program Files\dotnet\shared\Microsoft.NETCore.App\6.0.14\hostpolicy.dll], HRESULT: 0x80070057 An error occurred while loading required library hostpolicy.dll from [C:\Program Files\dotnet\shared\Microsoft.NETCore.App\6.0.14] Troubleshooting steps: Check the system event log for error messages Enable logging the application process' stdout messages Attach a debugger to the application process and inspect
这个时候就是可以需要安装一下KB2533623更新了，

这个是官方的更新下载地址，不过我现在打开里面的下载地址都提示404.我就在百度上自己找个这个更新的安装包。根据自己的系统下载相应的安装包。
