This is applicable only for the controls in the scope in which the resources are merged. You can see how to apply a theme different than the default one in the Setting a Theme (Using Implicit Styles) help article.Ĭhanging the theme using implicit styles will affect all controls that have styles defined in the merged resource dictionaries.
