 For the second option, you'll need to build a NuGet package out of your `.dll` file(s), host on a NuGet or MyGet feed, and depend on it directly.  You'll still need to set `allowUnsafe` to `true` in the `buildOptions` section of your `project.json`.  Here's an example (assuming `MyNativeLib` is a Nuget package at version `1.2.0`):
