质量与可靠性改进

BCL¹	通过使用并发字典来处理多线程访问，解决影响BinaryFormatter.GetType 信息中发生的线程争用问题。
WPF²	解决在数据网格单元格中影响 WPF 组合盒（或任何选择器）的问题，该问题可在单元格的数据项重新虚拟化时尝试更改其选择属性（选择索引、选定项、选定值）或从基础集合中删除。如果选择器的ItemSource属性是通过单元格的DataContext设置绑定的数据，则可能发生此情况。根据虚拟化模式和为选择属性声明的绑定，症状可能包括数据项属性的意外更改（为空），以及重复使用 UI 的其他数据项的意外显示（为空）以前附加到重新虚拟化的项目。解决了 WPF TextBox 或 RichTextBox 元素启用拼写检查崩溃并在某些情况下返回"执行引擎异常"错误的问题，包括在超链接附近插入文本。解决了影响每监视器感知 WPF 应用程序的问题，这些应用程序承载系统感知或不知道子窗口，并在 .NET Framework 4.8 上运行。此 .NET 版本偶尔会崩溃并返回"系统.集合.泛性.KeyNotFoundException"异常。
CLR³	解决了在重复加载和卸载 Mscoree.dll 的情况下可能导致句柄泄漏的问题。解决错误导致进程终止的罕见情况，而不是提供预期的NullReference 异常结果。

¹ 基本类库 (BCL) ²Windows 演示基础 (WCF)³ 公共语言运行时 (CLR)
