GLFW is a free, Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan application development. It provides a simple, platform-independent API for creating windows, contexts and surfaces, reading input, handling events, etc.

Glfw.Net is a set of C# bindings for GLFW. It's fully-documented and comes with all the original functions except for Vulkan-related features. Some functions and delegates have been slightly changed to take advantage of C# features and make it easier to use.

You'll find most of the original tests in Glfw.Tests, they're considered a good starting place. Below is a port of the example code from the GLFW documentation.

using Glfw3;
using OpenGL;
using System;

class Example
{
    static void Main(string[] args)
    {
        // If the library isn't in the environment path we need to set it
        Glfw.ConfigureNativesDirectory("../../External/");

        // Initialize the library
        if (!Glfw.Init())
            Environment.Exit(-1);

        // Create a windowed mode window and its OpenGL context
        var window = Glfw.CreateWindow(640, 480, "Hello World");
        if (!window)
        {
            Glfw.Terminate();
            Environment.Exit(-1);
        }

        // Make the window's context current
        Glfw.MakeContextCurrent(window);

        // Loop until the user closes the window
        while (!Glfw.WindowShouldClose(window))
        {
            // Render here
            Gl.Clear(ClearBufferMask.ColorBufferBit);

            // Swap front and back buffers
            Glfw.SwapBuffers(window);

            // Poll for and process events
            Glfw.PollEvents();
        }

        Glfw.Terminate();
    }
}

Glfw.Net doesn't have any library dependency but I recommend you use the excellent OpenGL.Net bindings. As for platform dependencies, Glfw.Net makes use of C# 6.0 features and has been tested with .Net Framework 4.5.2.

To build tests you'll need OpenGL.Net and CommandLineParser (both can be installed via NuGet).

This binding is heavily inspired by the work of others, mainly Chevy Ray Johnston and Robbie Lodico.

Like the original library, this work is released under the zlib/libpng license.
