我在App.xaml中为ProgressBar声明了以下样式

如您所见，已经提到了<Style x:Key="{x:Type ProgressBar}" TargetType="{x:Type ProgressBar}">，据我所知，这应该应用于应用程序中的所有ProgressBar。
我在Login.xaml页面中有以下ProgressBar，它保存在View文件夹下。
<ProgressBar Name="LoginProgress" Minimum="0" Maximum="100" HorizontalAlignment="Left"
Height="24" Margin="99,124,0,0" VerticalAlignment="Top" Width="109"
Style="{DynamicResource {x:Type ProgressBar}}">
</ProgressBar>
我还含蓄地提到了 ProgressBar Style属性。在所有这些之后，样式不会应用。搜索了谷歌中的所有页面，但无法完全获得适当的资源来理解，因此在这里。任何人都可以让我知道或提供更多关于如何做到这一点的见解吗？
请参考下面的堆栈溢出链接。这个问题在这里深入讨论。我想迪伦给出的答案应该会对你有所帮助。
x：Key="{x：Type TextBox}" 有什么作用？
