Answer 1

从您的错误消息中您可以看到 UseStaticFiles 可用于 DNX 4.5.1 框架但不可用于 DNX Core 5.0

您应该将对 Microsoft.AspNet.StaticFiles 的依赖项不仅添加到 dnx451 中，还应该添加到 项目中的 dnxcore50 中。 json.您可以删除 "frameworks" 键中的依赖项并将其放入 "dependencies" 键中，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": { }
  }

  ...
}
