我是 WPF 和 XAML 的新手，但是经过几个小时的谷歌搜索后，我无法弄清楚这里出了什么问题。我添加了 PresentationUI 程序集作为参考。
“类型引用找不到名为 'PresentationUIStyleResources' 的公共类型。第 14 行位置 44。”
错误发生在“PresentationUIStyleResources”的第一行。
我要做的是采用默认的 DocumentViewer 并删除打印按钮并找到文本框。然后我想添加更多的 cbuttons 和它们的功能。但是这个错误已经让我退缩了一段时间。有谁知道为什么？

注意：我几乎一直试图在 MSDN 上为此找到代码，这就是上面的内容。
