Description

Unions cannot have more than one logical type in C#.

The following code fails:

Schema schema = Schema.Parse(
"[\"null\",\n" +
" { \"type\": \"int\", \"logicalType\": \"date\" },\n" +
" { \"type\": \"long\", \"logicalType\": \"timestamp-millis\" }\n" +
"]");

 

The error is

 Avro.SchemaParseException : Duplicate type in union: logical at '[2]'
