XobotOS 介绍
XobotOS 是 Xamarin 的一个研究项目，用于移植 Android 4.0
的 Java/Dalvik 到 C# 语言。
XobotOS is a semi-automated port of the Android 4.0 source code from Java to
C#. The automated parts were ported using an improved version of Sharpen that
can compile more advanced Java constructs and supports generics. Most of the
manual bits of code fall in two categories (a) code to integrate with the host
operating system and (b) replace the Java JNI code used to call into C, with
the ECMA CLI P/Invoke functionality
