Key Features

• ImGui.NET Integration
  Provides a seamless backend for building GUIs using the popular Dear ImGui framework.
• Custom Win32 and DirectX11 Backend
  Hand-written and optimized for high performance, enabling smooth rendering and low latency.
• Efficient P/Invoke Usage
  Minimal marshaling ensures fast interop and reduced garbage collection pressure.
• Modern .NET Features
  Leverages .NET 6+ for clean, maintainable, and efficient code.
• Lightweight and Easy to Use
  Simple to integrate into any .NET application with minimal overhead.

Quick Start

Initialize the Wrapper

using ImGuiNET;

namespace App
{
    public class Program : UserInterface
    {
        override public void Render(){
            ImGui.ShowDemoWindow();
        }
        public static void Main()
        {
            Program program = new();
            program.Run("hello", 800, 600); 
        }
    }
}

Performance Optimizations

Custom Backend: Eliminates bloat for direct access to Win32 and DirectX11 APIs. Minimal Allocations: Static variables and efficient structs reduce GC pressure in critical loops. Zero-Cost Abstractions: Hand-written interop layers ensure predictable, high-speed performance.
