Research direction

The issue shows duplicate ToJson overloads when multiple schema top level definitions are used. To fix, examine how the C# renderer generates the Serialize class and deduplicates methods. Look at the handling of schema definitions in the quicktype source, particularly the C# renderer file. The reproduction is clear: use two top level definitions in the schema. The fix likely involves deduplication logic or ensuring unique method signatures.
