c# - 使用 Xceed.Wpf.Toolkit 中的 MaskedTextBox 时出现 SetConnectionId 异常

Question

我将为我的 wpf 项目使用 MaskedTextbox，这样我就可以拥有一个带有 Mask 的文本框。我对如何使用它完全陌生。说明是下载扩展的 wpf 工具包，将其引用到您的项目中，它将起作用。

所以当我构建项目时，没有显示任何错误。但是，当我尝试转到有屏蔽文本框的表单时，发现错误“Set connectionId throw an exception”。希望有人知道解决方案。我试着像我看到的一些帖子一样重建它，但仍然无济于事。我的 xaml 代码是:
