在 MonoTouch 游轮上，耳朵后面湿透了。
我遵循 Xamarin 网站上的 Hellow World tut 的步骤；http://docs.xamarin.com/ios/getting_started/hello_iphone
1) 通过 App Store 安装 XCode
2) 从 Xamarin 站点全新安装 MonoDevelop
在 MonoDevelop 中创建了新项目“HelloApple”（单视图应用程序）。
构建应用程序（命令+B）。
使用 XCode Interface Builder 打开生成的 HelloApple_UIViewController.xib 文件
单击运行按钮。
收到以下错误；

架构 i386 的未定义符号：“_main”，引用自：从 crt1.o 开始 ld：未找到架构 i386 的符号 clang：错误：链接器命令失败，退出代码为 1（使用 -v 查看调用）
我已经卸载了 XCode 和 MonoDevelop，以为我做了几次乱七八糟的事情。真是难住了。我认为这个例子可以解决问题，所以我必须在这里遗漏一些东西。StackOverflow 上的几篇文章都围绕着更复杂的已经构建的应用程序展开，这并没有为项目添加任何东西，即开箱即用。
我错过了什么？
