我已将使用 lync sdk 程序集的现有应用程序更新到 silverlight 5。从那里开始，应用程序无法编译给出错误 XML 命名空间 'clr-namespace:Microsoft.Lync.Controls; 中不存在标签'UCTreeView'； assembly=Microsoft.Lync.Controls' 我添加了以下参考 Microsoft.Lync.Controls
Microsoft.Lync.Controls.Framework
Microsoft.Lync.Model
Microsoft.Lync.Utilities
System.Windows.Controls
以下 XAML 给出了编译错误
