这里应该不需要设置DisplayMemberPath

ViewModel.ElementTheme是什么类型的？应该和ItemsSource绑定的数组的元素类型一致

@dodu2014 I just ran into this same issue on Windows 11.

See this explanation: https://stackoverflow.com/a/39379568/390982

Simply put, the ElementTheme enumeration is not a .net type, and does not act like a .net enum. You (and I) will need to define a custom enum, or devise another way to mock the enumeration.
