我正在创建一些 WPF（自学）。 我相信它是在 VS2021 中创建的，但是我的电脑死了（主板）。 我已经在新电脑上重新安装了所有内容并带来了备份，然后安装了 VS2022。
打开后，我的 app.xml 样式部分出现大量错误 (30)。 这工作正常，奇怪的是仍然可以运行和编译，但显然我没有做正确的事情。
有趣的是，有些部分有效，而其他部分则无效。 主要不起作用的是引用顶部的 SOLIDCOLORBRUSH，它正在为应用程序设置颜色。
主要错误是：
错误 XDG0062“StaticResourceExtension”对于 Setter.Value 无效。 唯一支持的 MarkupExtension 类型是 DynamicResourceExtension 和 BindingBase 或派生类型。
错误 XDG0062 资源“brdrTeal”具有不兼容的类型。
错误 XDG0062 'txtTitle' 资源未找到。
这些都是通过 {StaticResource XXXXX} 引用的
最后这一段出现了这个错误：
错误：
错误 XDG0062“{DependencyProperty.UnsetValue}”不是有效值 对于 'System.Windows.Controls.Control.Template' 属性 二传手。
代码：

<Setter Property="Template">

我在下面包含了 app.xaml 文件的一部分，以查看我如何布置所有内容。 如果这是一种不正确的方法，我热衷于正确地做到这一点，因为我的意思是我现在刚刚学习这个。

动态值需要DynamicResource。 改变例如
Background="{StaticResource Teal5}"
到
Background="{DynamicResource Teal5}"
