DotNetCppExample

This is an example project showing how to pass data and functions back and forth across .NET and C++ on Linux and Windows with one cross-platform .NET build using the new .NET Core 2.0 framework. This is useful if you are using a cross-platform .NET framework, but want to let various components be composed of native code, built for the specific OS.

Prerequisites

.NET Core 2.0 (download)

Visual Studio (download) or your preferred method for compiling C++ on Windows

The GNU C++ compiler (g++) or your preferred C++ compiler for Linux

Building

1. Build the C++ Library

For Linux:

cd CppLibrary/CppLibrary/
make all

For Windows

• Open the CppLibrary.sln solution in Visual Studio
• Click Build

2. Build the .NET solution

Build on the command line (Linux or Windows)

cd DotNetClient/
dotnet build DotNetClient.sln

or

• Open the DotNetClient/DotNetClient.sln solution in Visual Studio
• Build

Running

To run the DotNet Core 2.0 example program, you will use the dotnet application:

cd DotNetClient
dotnet DotNetClient/bin/x64/Debug/netcoreapp2.0/DotNetClient.dll

This example code works on both Linux and Windows (although on Windows, s/\//\\/g).

** Note that at this point, the program will only run from this directory, as the library locations have been hardcoded. See Issue #3.
