将WPF xaml转换为Silverlight xaml

除了一件事之外，我几乎成功地把它全部转化了

这是有问题的部分-

<ContentPresenter Margin="2,2,2,2" x:Name="PART_SelectedContentHost" ContentSource="SelectedContent"/>

这是整个xaml（不太长）——

ContentSource
不是Silverlight中
ContentPresenter
控件的依赖属性。不幸的是，我不知道Silverlight中的use/equillant属性，所以我要查看msdn文档，了解如何迁移该值(http://msdn.microsoft.com/en-us/library/system.windows.controls.contentpresenter（v=vs.95）.aspx）
谢谢@Dave S，那么我应该在那里写些什么呢？我不确定，正在设置的SelectedContent值是多少？-在一个猜测，它似乎只是内容，所以尝试使用内容dp代替。
