Csharp Avro C# 使用跨多个模式文件定义的类型生成类

我正在使用Apache.Avro包从一些Avro模式生成一些C#.我有共享公共构建块(如Enum定义)的不同架构.

我遇到了对公共共享模式的引用不能正确解析的问题.

以下是在一个文件中定义的模型:

{
    "name": "MyModel",
    "namespace": "My.Model",
    "type": "record",
    "fields": [
        {
            "name": "Planet",
            "type": "My.Model.PlanetEnum",
        }
    ]
}

以下是My.Model.PlanetEnum的定义，它将在多个车型之间共享:

{
  "name": "PlanetEnum",
  "namespace": "My.Model",
  "type": "enum",
  "symbols": [
    "Earth",
    "Mars"
  ]
}

下面是我用来生成模式的C#:

        var codeCompileUnit = new CodeGen
        {
            Schemas =
            {
/* generation fails even if I include the enum definition inline here
                Schema.Parse("""
{
  "name": "PlanetEnum",
  "namespace": "My.Model",
  "type": "enum",
  "symbols": [
    "Earth",
    "Mars"
  ]
}
"""),
*/
                Schema.Parse(schemaText)
            },
        }.GenerateCode();

        var stringWriter = new StringWriter(new StringBuilder());
        var provider = CodeDomProvider.CreateProvider("csharp");
        provider.GenerateCodeFromCompileUnit(codeCompileUnit, stringWriter, new CodeGeneratorOptions());
        var schemaCode = stringWriter.ToString();
        return schemaCode;

我得到的错误是:

Avro.SchemaParseException: Undefined name: My.Model.PlanetEnum at 'fields[0].type'
