Question

我正在使用WPF文本框拼写检查器：

<TextBox ... SpellCheck.IsEnabled="{Binding EnableSpelling}"... />

如你所见，它绑定到我的VM中的bool属性，告诉它是否拼写检查此框。这似乎在很大程度上起作用，但是我遇到了一些偶尔会出现错误的用户。令我感到困惑的是，堆栈跟踪根本没有显示我的代码......这是跟踪：

The given key was not present in the dictionary.

我环顾四周但找不到这样的东西。很多“关键不存在”的错误，但没有拼写检查或我能找到的这样的错误。我理解一个未找到密钥的错误是什么，但它使用了什么字典以及如何修复它，因为堆栈完全在.NET框架而不是我的代码中？

拼写检查错误？
