From your error message you can see that UseStaticFiles is available to DNX 4.5.1 framework but not to DNX Core 5.0

You should add the dependency to Microsoft.AspNet.StaticFiles not only to dnx451 but also to dnxcore50 in your project.json. You can remove the depency in the "frameworks" key and put it inside the "dependencies" key to make it available for both frameworks

{
  ...

  "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": { }
  }

  ...
}
