Resources allow objects to be reused throughout a WPF application. Resources are managed through a ResourceDictionary and can have different scopes like system, application, window, or element. Settings allow application preferences to be stored and loaded using the ApplicationSettingsBase class and can be integrated with WPF data binding.

Preferred settings mechanism by ApplicationSettingsBase class
from the System.Configuration namespace

Lesson 09 Resources and Settings in WPF
- 3. A resource is an object that can be reused in different places in your application. Resources allow you to define object for use in you application and share object among elements Any object in WPF can be a resource WPF use ResourceDictionary class to manage resources and FrameworkElement base class to work with resources ResourceDictionary like a Hashtable (key/object)
- 4. System scope Configure at a system-wide level Example: brushes, fonts, and metrics… Application scope Used throughout your application Useful for styles or control templates Windows scope Used throughout windows Element scope Used internal the element
- 5. Designing Settings Preferred settings mechanism by ApplicationSettingsBase class from the System.Configuration namespace Designer support Two type: User/Application settings Using settings Load: Properties.Settings.Default.[Your setting] Save: Properties.Settings.Default.Save(); Integrating withWPF databinding <TextBlock Text="{Binding Path=MyAppSettings, Source={x:Static local:Properties.Settings.Default}}" />
Editor's Notes
- #4: At the heart of resource management is the ResourceDictionary class. Outwardly, this is just a simple collection class. It behaves much like an ordinary Hashtable—it allows objects to be associated with keys, and it provides an indexer that lets you retrieve those objects using these keys. So, in theory, you could use the ResourceDictionary like a Hashtable For example, the FrameworkElement base class, from which most user interface elements derive, provides a resource dictionary in its Resources property
