If you have merged resource dictionary using code like below

Then, instead of Application.Current.Resources["ResourceKey"] you need to specify Control name (in this case MainWindow) also like below

var style = Application.Current.MainWindow.Resources["ResourceKey"];
// OR
var style = Application.Current.MainWindow.TryFindResource("ResourceKey");
