What is the mocking framework of choice in Unit Test Library for Windows Store Applications?

When I write unit tests I like to use Rhino Mocks.

So when I started my first Windows Store application I naturally started with my unit tests first. When I tried to add RhinoMocks via NuGet I recieved the following error

Could not install package 'RhinoMocks 3.6.1'. You are trying to install this package into a project that targets '.NETCore,Version=v4.5', but the package does not contain any assembly references that are compatible with that framework. For more information, contact the package author.

I had the same issue with Moq.

Is there a mocking framework for .NETCor,Version=v4.5?
