FrameworkPropertyMetadata Constructor (Object)
Initializes a new instance of the FrameworkPropertyMetadata class with the specified default value.
Assembly: PresentationFramework (in PresentationFramework.dll)
The type of the value provided for defaultValue must match or be related to the type specified in the original registration of the dependency property that this metadata will be applied to. Mismatches between metadata default value type and the type of the dependency property it is being applied to can be difficult to debug, because the mismatch is not detectable during compilation. The property system does not evaluate the effective value of a property until run time, so the result of a default value type/property type mismatch is a run-time error.
The value UnsetValue has special meaning in the property system, and cannot be used as a dependency property default value.
