Resources

• Identified by unique key, implicit or explicit [x:Key directive].

• Can be created/overwritten in the Resources section for a FrameworkElement/FrameworkContentElement or Application. Can also be defined in Resource Dictionaries and merged with Application resources.

• Recommended creation at the minimum level possible.

• Binding.Source uses them with StaticResource or DynamicResource.

Types with default constructor

• Can be instantiated directly in the Resources section. Their public properties can be set in XAML which can also be a source for binding

XmlDataProvider

• Enables declarative access to XML node tree from the inline XML data, XML data file, or XmlDocument. It is the slower among the two data providers

ObjectDataProvider

• Allows instantiation using specific constructor. Can also use any method of the type for data with specific parameters. The parameters can also be used as a binding source.

• Binding.BindsDirectlyToSource: When true, specifies that the binding path is relative to the Data property.
