Hi mcosmin ,
If you want to call winRt , you could add reference to it , you could find it in C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETCore\v4.5.

Please refer to

But if you want cryptography classees , there should be other lib you could use. I think you it is not necessary that you use winRt.
Best regards,
