Answer 1

从错误消息中，您可以看到UseStaticFiles框架可以使用DNX 4.5.1，但DNX Core 5.0

可以使用Microsoft.AspNet.StaticFiles

您应该将依赖关系dnx451添加到dnxcore50，但也应添加到project.json的{​​{1}}。您可以删除"frameworks"密钥中的依赖项，并将其放在"dependencies"密钥中，以使其可用于两个框架

{
  ...

  "dependencies": {
    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-beta8",
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-beta8",
    "Microsoft.AspNet.StaticFiles": "1.0.0-beta8",
  },

  ...

  "frameworks": {
    "dnx451": { },
    "dnxcore50": { }
  }

  ...
}
