Extend an open JSON Schema type with new properties using $ref — similar to deriving from a base class in C#. Corvus.JsonSchema combines both schemas into one type.

JSON Schema objects are open by default, allowing extra properties for forwards compatibility — use unevaluatedProperties to close them for strict validation.

Use $ref and $defs to extract shared schema definitions and reuse them across properties. Corvus.JsonSchema generates a single shared .NET type, eliminating duplication.

Add required fields, string length limits, and numeric range constraints to a JSON Schema data object — and see how Corvus.JsonSchema enforces them in C#.

Define a simple data object in JSON Schema and generate strongly typed C# with Corvus.JsonSchema — properties, implicit conversions, and fast serialization.

Corvus.JsonSchema enables safe use of the very high performance JSON parsing offered by .NET's System.Text.Json.
