Edm.Binary and null support in table storage entities

[huguesv]

I do not know if the null support is complete, and if that translates into entity properties being None. One thing I have noticed is that sending an entity with a None property and then querying for that entity back will give you an entity that doesn't have that Property.

In any case, this issue is a reminder for us to review Edm.Binary, null and None.

[huguesv]

Support for Binary is similar to the Azure SDK for the other languages: When Edm.Binary EntityProperty is seen, it is automatically converted to/from base64.

[huguesv]

Support for None is: m:null attribute is set on the way out to azure, and azure treats that EntityProperty as if it wasn't part of the entity. So when you query that entity back, the property is missing.
