C++ console test app for a Runtime Component Library(C++/WinRT)

  c++, c++-winrt

I need to create a C++/WinRT library for a BLE device. And also I need to create a test app for testing the APIs in the library. I am just a start learner of this new technology.

What are the different ways to use the C++/WinRT library(dll) functions in a C++ console test application?
If multiple ways are there, which one is better?

Could any kind soul shed some light? Thanks a lot!
