A string that represents the ResourceKey property of the requested resource object.
Type: System.Object An Object that represents the requested application-level resource object; otherwise, null if a resource object is not found or if a resource object is found but it does not have the requested property.
In some editing environments, such as Visual Web Developer, the editor might throw a design-time MissingManifestResourceException exception if you use a period (.) in the global resource-key name. However, this does not affect your ability to edit or save the file, and you can ignore the error.
