Example exporting CPP class as DLL and importing in Unity C# as native plugin

There will be times when you want to run your C++ code inside Unity. So you will need to export the code into DLL format and then import it in Unity. This project is showing you an example of exporting a Student class written in C++, and import it in Unity C#.

How to run NOW

Open Unity project TestImportCPPClass and press Play button or Ctrl+P. You will see the output is being printed in the console.

Then take a look at TestImportCPPClass/Assets/TestImportCPPClass.cs to see how it is implemented.
You will see quickly that it's just a bunch of function calls to the DLL files.

How to reproduce result from scratch

Open Visual Studio 2017 and create a new DLL project.
Copy content of file TestExportCPPClass.cpp from TestExportCPPClass/TestExportCPPClass/ directory.
Go to Build -> Build solution, make sure the build is set to x64 to get a
dll file ready for Unity project with x64 architecture.
(Optional: You could also build x86 version too)
Create a new Unity project.
Copy dll file from TestExportCPPClass/x64/Debug into Unity's Assets/Plugins/x86_64 directory.
Open Unity project and copy the C# script from TestImportCPPClass/Assets/ directory.
Create an empty GameObject in the scene and attach the script to it.
Press Play button to see the output in the console.
