uwp Tutorial => 3. Merged Dictionaries

Example

Almost usually things are a little bit more complex and to support scalability we should split things apart. So we can define various files containing different resources dictionaries, i.e. resources for UI controls' themes, resources for texts and so on, then we merge them all together in App.xaml file.

Snippet from App.xaml

<Application
    x:Class="MyNewApp.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    RequestedTheme="Dark">

    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/Assets/Themes/GeneralStyles.xaml"/>
                <ResourceDictionary Source="/Assets/Themes/TemplatedControls.xaml"/>
                <ResourceDictionary Source="/Assets/Strings/Texts.xaml"/>
                <ResourceDictionary Source="/Assets/Strings/ErrorTexts.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

You can create a new dictionary file by right clicking on Asset folder [Add -> New Item]
