Description

For .NET/#C nullable types is supported by union.

But union is not supported for properties with converter (general or attribute). As a result to support nullable types we need have separate converter for it. As a result it cause a lot of code duplicate.

For example for DateTime type there should be one converter and for DateTime? another one.

Support union for properties with converters can be beneficial for those who use ReflectReader/Writer.
