StaticResource refers to a Xaml Markup Extension implemented as part of the Windows Presentation Foundation (WPF) Resource Model.
The Windows Presentation Foundation (WPF) provides a mechanism for referencing objects that are shared across modules, or used to enhance one or more framework elements.
Static resources are used to refer to objects or values that have been previously defined in the Xaml object graph. Each static resource is identified by a key, and the key must conform to the Xaml Name Grammar specification
This tag is appropriate for questions that involve the StaticResource markup extension or its syntax; however, the use of other tags may be more appropriate and attract a broader audience. Alternate tags are: Data Templates, Control Templates, Style, Data Context, ObjectDataProvider plus other tags that convey a focus on Xaml technology.
