推荐答案

接受的答案会告诉您问题，但没有告诉您如何解决它.我只会为以后的访问者添加这个.要解决这个问题，需要添加对PresentationFramework.dll的引用.

The accepted answer tells you the problem but does not tell you how to solve it.I'll just add this for future visitors. To solve this problem, you need to add the reference to PresentationFramework.dll.

1 转到 Solutions Explorer(它位于 IDE 的右侧)> 右键单击​​ References

1 Go to Solutions Explorer (it's on the right of your IDE) > Right click on References

2 选择添加引用

在打开的窗口中，查找Presentation Framework，选中该框并单击确定.就这样.这是向项目添加引用的方法.

in the window that opens, look for Presentation Framework, check the box and click okay. That's all. This is the way to add references to your project.
