You cannot reference a .NET assembly LINQ to a UWP C++ project. You can only reference the UWP Windows Runtime Component to it.

Answer 2

Right-click on "References" in the solution explorer, and click "Add reference" in the pop-up menu. That will open the reference manager where you can select the reference you need. You can read more about the topic in this MSDN article .
