+Additions allow you to add arbitrary C# to the generated classes
+before they are compiled. This can be helpful for providing convenience
+methods or adding pure C# classes.
+
+== Adding Methods to Generated Classes ==
+
+Let's say the library being bound has a Rectangle class with a constructor
+that takes an x and y position, and a width and length size. It will look like
+this:
+
+public partial class Rectangle
+{
+ public Rectangle (int x, int y, int width, int height)
+ {
+ // JNI bindings
+ }
+}
+
+Imagine we want to add a constructor to this class that takes a Point and
+Size structure instead of 4 ints. We can add a new file called Rectangle.cs
+with a partial class containing our new method:
+
+public partial class Rectangle
+{
+ public Rectangle (Point location, Size size) :
+ this (location.X, location.Y, size.Width, size.Height)
+ {
+ }
+}
+
+At compile time, the additions class will be added to the generated class
+and the final assembly will a Rectangle class with both constructors.
+
+
+== Adding C# Classes ==
+
+Another thing that can be done is adding fully C# managed classes to the
+generated library. In the above example, let's assume that there isn't a
+Point class available in Java or our library. The one we create doesn't need
+to interact with Java, so we'll create it like a normal class in C#.
+
+By adding a Point.cs file with this class, it will end up in the binding library:
+
+public class Point
+{
+ public int X { get; set; }
+ public int Y { get; set; }
+}
