NativeExposer

Do not write glue code yourself!

Preserving all API data, NativeExposer generates glue codes automatically to host C# from C++, without NativeAOT or IPC:

• C#

class Program
{
    [Export]
    public Program() {}

    [Export]
    public void Hello() {
        Console.WriteLine("Hello, World");
    }
}

• C++

clr::assert(clr::init("<dotnet-root>", "<runtimeconfig.json>"));
clr::assert(clr::load("<your-dll>"));

Program program;
program.Hello();

clr::close();

Getting Started

1. Install NativeExposer.Build to system

dotnet tool install -g NativeExposer.Build

It installs native-exposer build tool to your system.

2. Add NativeExposer to csproj as dependency

<PackageReference Include="NativeExposer" Version="1.0.0"/>

3. Use custom builder to generate stubs

native-exposer <csproj> <output-path>

It generates CMakeLists.txt, lib.cxx and lib.h. You can use this CMakeLists.txt from your CMake project as add_subdirectory or etc...

4. Enjoy it!

Requirements

• .NET 5 or above

Current Limitation

• Cannot export properties
• Broken when trimming or NativeAOT
