[jira] [Comment Edited] (AVRO-2359) Support Logical Types in C#
[ https://issues.apache.org/jira/browse/AVRO-2359?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16804008#comment-16804008 ]

------------------------------------------------------------
I've opened an early PR (see Issue Links) for on-going review. The work is not complete but I'd appreciate early feedback in order to determine if there are things that I've missed or overlooked.
I believe that I've covered the 'core' of the changes needed to support logical types in C#, but all of the logical types outlined in the current specification need implementations (I currently only have "date").

> By not supporting Logical Types, the C# Avro implementation is severely limited in terms of its interoperability in heterogeneous environments. While the implementation will safely ignore logical type declarations in processed schemas; at runtime the semantics of a "date" for example, will be lost when receiving an Avro payload that was encoded by the Java platform using the same schema. The C# implementation will never be able to retrieve the date value from the encoded int.
> I propose that the C# Avro implementation be extended to support the Logical Types as defined by the current specification. I have also explored the lang/csharp codebase and believe that I could produce a PR to support this.
