> C# Primitive Schema losing metadata
> -----------------------------------
>
> Key: AVRO-2862
> URL: https://issues.apache.org/jira/browse/AVRO-2862
> Project: Apache Avro
> Issue Type: Bug
> Components: csharp
> Affects Versions: 1.9.2
> Reporter: Cody
> Assignee: Martin Tzvetanov Grigorov
> Priority: Major
> Fix For: 1.11.1, 1.12.0
>
>
> Using this ticket as a base reference:
> https://issues.apache.org/jira/browse/AVRO-1545
> The same problem is happening in the C# version as well.
> Given:
> {code:java}
> {
> "type" : "record",
> "name" : "BrokenRecord",
> "namespace" : "whatever",
> "fields" : [
> {
> "name" : "a_string",
> "type" : {
> "type" : "string",
> "foobar" : "some example here"
> }
> }
> ]
> }
> {code}
> The property "foobar" will be lost when parsing the schema.
> The fix that my team has implemented is modifying this line (file used from
> release 1.9.2)
>

> And replacing it with the following:
> {code:java}
> if(this.Props != null && this.Props.Count > 0)
> {
> w.WriteStartObject();
> w.WritePropertyName("type");
> w.WriteValue(Name);
> foreach(var prop in Props)
> {
> w.WritePropertyName(prop.Key);
> w.WriteRawValue(prop.Value);
> }
> w.WriteEndObject();
> }
> else w.WriteValue(Name);{code}
