 Windows Vista introduced a new style of common file dialogs. As of .NET 3.5 SP1, the Windows Forms `OpenFileDialog` and `SaveFileDialog` class will automatically use the new style under most circumstances; however, some settings (such as setting `ShowReadOnly` to `true`) still cause it to revert to the old dialog. The `FolderBrowserDialog` still uses the old style. In WPF, the `Microsoft.Win32.OpenFileDialog` and `SaveFileDialog` classes still use the old style dialogs, and a folder browser dialog is not provided at all.
