WPF依賴屬性Binding實現

由於最近一段時間一直沒有做相關方面的東西，導致好多東西都忘了，就一個依賴屬性綁定還倒騰了一下。特專門把相關的實現方式存留在博客園

XAML部分，其中有一大塊是實現樣式的，如果有需要的可以看看，其實只要把握住這么個關鍵點就行了，在后台定義依賴屬性，xaml部分一定要記得給窗體Name屬性賦值，就比如我這里給的

 x:Name="mainWindow"
再就是在binding的時候的寫法

Content="{Binding ElementName=mainWindow, Path= MyContent}"
這樣的話就可以大功告成了。

這段代碼中還有有關spring.net的東西，所以可能比較雜亂。
