UWP C # Call C++/CX

Create a UWP Project

Then create a generic C + + run-time project

Right-click on the C + + project and add a C + + class

Defining a class in a header file

Introducing in the CPP file

#include "pch.h"
Introducing C + + projects in a UWP project

Classes defined in C + + can be used directly in UWP C #

     Public Sealed Partial classMainpage:page { PublicMainPage () { This.            InitializeComponent (); IMAGEFACTORYRT.IMAGESRC imagesrc=Newimagesrc (); List<int> list =Newlist<int>(); List. ADD (3); List. ADD (2); List. ADD (1); IMAGESRC.LOADIMAGESRC (list,3,2); Imagesrc.width=1; inth =Imagesrc.height; }    }

The main purpose of this is to encapsulate the standard C + + class library using [Standard C + +] ==> [c++/cx] ==> [UWP C #]. Audited by Win10 store.
