dotnet部署出现Failed to load the dll from [ ... hostfxr.dll], HRESULT: 0x80070057

try

1. When prompted, try to install the corresponding platform version of the .net core, still does not work, suggesting misleading
2. Based on a keyword search, we found long been stepped pit too, need to install the KB2533623patch

solve

Go to
Microsoft Security Bulletin: insecure library loading could allow remote code execution

ps.
remember six years ago to try
