(Refer to /tree/master/FlysTest)

• Final result:
• Create a Windows-form application
• Delete the entire Form1 class
• Install the FlysEngine nuget package
• Install the SharpDX.Desktop nuget package for convenient
• In Program.cs file, using following namespaces:

  using FlysEngine;
  using FlysEngine.Managers;
  using SharpDX;
  using SharpDX.Direct2D1;
  using SharpDX.Windows;
  using System;
  using System.Windows.Forms;
  
  using DWrite = SharpDX.DirectWrite;
  

• Replace Main method's content to following code:

  using (var res = new XResource())
  using (var form = new Form() { Text = "Hello World" })
  {
      var timer = new RenderTimer();
      var bottomRightFont = new DWrite.TextFormat(res.DWriteFactory, "Consolas", 16.0f)
      {
          FlowDirection = DWrite.FlowDirection.BottomToTop, 
          TextAlignment = DWrite.TextAlignment.Trailing, 
      };
      var bottomLeftFont = new DWrite.TextFormat(res.DWriteFactory, "Consolas", 
          DWrite.FontWeight.Normal, DWrite.FontStyle.Italic, 24.0f)
      {
          FlowDirection = DWrite.FlowDirection.BottomToTop, 
          TextAlignment = DWrite.TextAlignment.Leading, 	
      };
  
      form.Resize += (o, e) =>
      {
          if (form.WindowState != FormWindowState.Minimized && res.DeviceAvailable)
          {
              res.Resize();
          }
      };
  
      RenderLoop.Run(form, () => Render());
  
      void Render()
      {
          if (!res.DeviceAvailable) res.InitializeDevice(form.Handle);
  
          var target = res.RenderTarget;
  
          timer.BeginFrame();
          target.BeginDraw();
          Draw(target);
          target.EndDraw();
          res.SwapChain.Present(1, 0);
          timer.EndFrame();
      }
  
      void Draw(DeviceContext target)
      {
          target.Clear(Color.CornflowerBlue.ToColor4());
          RectangleF rectangle = new RectangleF(0, 0, target.Size.Width, target.Size.Height);
  
    	  target.DrawRectangle(
              new RectangleF(10, 10, target.Size.Width - 20, target.Size.Height - 20), 
              res.GetColor(Color.Blue));
  
          target.DrawText("😀😁😂🤣😃😄😅😆😉😊😋😎", 
              res.TextFormats[36],  rectangle, res.GetColor(Color.Blue), 
              DrawTextOptions.EnableColorFont);
  
          target.DrawText("FPS: " + timer.FramesPerSecond.ToString("F1"), 
              bottomRightFont, rectangle, res.GetColor(Color.Red));
  
          target.DrawText("Hello World",
              bottomLeftFont, rectangle, res.GetColor(Color.Purple));
      }
  }
