Create Themes

Now it’s time to create our own personalization theme.

  • Create a folder and name it Preset.
  • Create 2 more folders in this folder called Default and MyTheme

You can choose other names for folders

  • In each of these 2 folders, create 2 ResourcesDictionary named Light.xaml and Dark.xaml

So we have:

--Preset
  |
  --Default
    |
    --Light.xaml
    --Dark.xaml
  --MyTheme
    |
    --Light.xaml
    --Dark.xaml

You can leave the dictionaries for the default folder blank, This is for when you want to clear your personalization and get back to normal

  • Now open the MyTheme Light and Dark dictionary and Expand MergedDictionaries then define a ColorPaletteResources
