- Build Adobe Air Native Extensions using C#
The package is hosted on NuGet at https://www.nuget.org/packages/TuaRua.FreSharp/
A basic Hello World starter project is included
The following table shows the primitive as3 types which can easily be converted to/from C# types

return i.ToFREObject() |
| Boolean | bool | var b = argv[0].AsBool() |
return b.ToFREObject() |
| Number | double | var dbl = argv[0].AsDouble() |
return dbl.ToFREObject() |
| uint ARGB | Color | var clr = argv[0].AsColor() |
return clr.ToFREObject() |
| Date | DateTime | var dt = argv[0].AsDateTime() |
return dt.ToFREObject() |
| Rectangle | Rect | var rect = argv[0].AsRect() |
return rect.ToFREObject() |
| Point | Point | var pnt = argv[0].AsPoint() |
return pnt.ToFREObject() |
| BitmapData | Bitmap | var bmp = argv[0].AsBitmap() |

}Advanced: Extending FreObjectSharp. Creating a C# version of flash.geom.point
using FREObject = System.IntPtr;
using Point = System.Windows.Point;
public static class FrePoint {
public static FREObject ToFREObject(this Point value) {
return new FREObject().Init("flash.geom.Point", value.X, value.Y);
}
public static Point AsPoint(this FREObject inFre) {
dynamic fre = new FreObjectSharp(inFre);
return new Point(fre.x, fre.y);
}
}com.tuarua.fre.ANEUtils.as and com.tuarua.fre.ANEError.as are required by FreSharp and should be included in the AS3 library of your ANE
Starting from version 2.2.0 FreSharp.ane is required in your AIR project.
This ANE contains the required FreSharp dlls and also handles the searching for and loading of a project's C# dll when packaged inside the ANE.
No more copying these files into your AIRSDK!
