When working in C#, you typically use one of two framework methods to look up a resource by its x:Key : :
: Returns null if the key is not found, rather than throwing an exception.
: When the resource is critical and its absence indicates a developer error. TryFindResource(object key) : Behavior : Follows the same lookup logic as FindResource .
: Throws a ResourceReferenceKeyNotFoundException if the key is not found.
