Description

Default converters can be added for a given Avro type and a Property type.  For example, to map a long to a DateTimeOffset.  However, if the class property is nullable, the default converter is not used.

 

Avro reflection should find the converter to use for nullable primitives.  It can also be helpful and provide automatic translation from non-nullable converters to nullable ones.  This allows a client to create one non-nullable converter that can be used for nullable properties.
