Application.LoadComponent Method (Uri)
Loads a XAML file that is located at the specified uniform resource identifier (URI), and converts it to an instance of the object that is specified by the root element of the XAML file.
Assembly: PresentationFramework (in PresentationFramework.dll)
You must explicitly convert the return value to the same type as the root element of the XAML file.
The XAML file can be an application code file (configured as an Microsoft build engine (MSBuild) Page item) or an application data file (a resource file, content file, or site-of-origin file; see WPF Application Resource, Content, and Data Files).
