Description

The Specific API in the C# bindings do not properly handle:

• Schemas with IList in their name
• Schemas with Nullable in their name
• Arrays of nullables (see example schema below)

These throw an exception from the ObjectCreator indicating that it could not find the type.

This sample application on GitHub demonstrates these problems: https://github.com/blachniet/AVRO-2522.

Here's a sample schema containing an array of nullables that triggers this problem.

{
  "namespace": "AvroListOfLists.Records",
  "name": "MyRecord",
  "type": "record",
  "fields": [
    {
      "name": "MyList",
      "type": {
        "type": "array",
        "items": ["null", "int"]
      }
    }
  ]
}
