Java call C# lib build with .NET CORE 2.0 via C++ as wraper The code is based on example from coreCLR

Java using JNI to call C++ code. then C++ host a core CLR to run C# code.

JDK: You should edit the Makefile and set the JAVALIB PATH

.NET CORE SDK 2.0: I only tested it in Ubuntu 16.04 x64

gcc 6: std C++ 14 for the filesystem

cmake . cmake --build .

java -cp sample1.jar Sample1

You should keep the compiled file in the same fold.
