適用於：

微軟 .NET 框架 4.8

2019 年 9 月 24 日，Windows 7 服務包 1 （SP1）和 Windows 伺服器 2008 R2 SP1 的更新包括 Microsoft .NET 框架 4.8 中的累積可靠性改進。我們建議您應用此更新作為常規維護常式的一部分。安裝此更新之前，請參閱先決條件和重新開機要求部分。

重要

從 2019 年 8 月開始，對 .NET Framework 4.6 以及更高版本的 Windows 伺服器 2008 SP2、Windows 伺服器 2008 R2 SP1 和 Windows 7 SP1 的更新需要 SHA-2 代碼簽名支援。為避免安裝問題，請確保在應用此更新之前已安裝所有最新的 Windows 更新。有關 SHA-2 代碼簽名支援更新的詳細資訊，請參閱KB 4474419。

品質和可靠性改良功能

BCL¹	通過使用併發字典來處理多執行緒訪問，解決影響BinaryFormatter.GetType 資訊中發生的執行緒爭用問題。
WPF²	解決影響 DataGrid 儲存格中的 WPF 組合盒（或任何選擇器）的問題，該問題可在儲存格的資料項目重新虛擬化時嘗試更改其選擇屬性（選擇索引、選定項、選定值）或從基礎集合中刪除。如果選擇器的ItemSource屬性是通過儲存格的DataCoNtext設置綁定的資料，則可能發生此情況。根據虛擬化模式和為選擇屬性聲明的綁定，症狀可能包括資料項目屬性的意外更改（為空），以及重複使用 UI 的其他資料項目的意外顯示（為空）以前附加到重新虛擬化的專案。解決了 WPF TextBox 或 RichTextBox 元素啟用拼寫檢查崩潰並在某些情況下返回"執行引擎異常"錯誤的問題，包括在超連結附近插入文本。解決了影響每監視器感知 WPF 應用程式的問題，這些應用程式承載系統感知或不知道子視窗，並在 .NET Framework 4.8 上運行。此 .NET 版本偶爾會崩潰並返回"系統.集合.泛性.KeyNotFoundException"異常。
CLR³	解決了在重複載入和卸載 Mscoree.dll 的情況下可能導致控制碼洩漏的問題。解決錯誤導致進程終止的罕見情況，而不是提供預期的NullReference 異常結果。
