## What it is
NJsonSchema is a .NET library for reading, generating, and validating JSON Schema draft v4+ documents. It can generate schemas from .NET classes and generate C# or TypeScript code from schemas.

## Use cases
- validate  payloads against a  schema in .net
- generate  schema from c# classes
- generate c# classes from a  schema
- generate typescript interfaces from a  schema
- read and write  schemas from yaml

## When to choose
- you need  schema support in a .NET application
- you want bidirectional mapping between .NET types and JSON Schema
- you need C# or TypeScript code generation from schemas

## When to avoid
- you work outside the .NET ecosystem
- you need full support for the latest JSON Schema draft features beyond v4+

## Facets
- artifact type: library
- maturity: stable
- function: serialization, parser, form-handling
- domain: developer-tools, apis, files
- platform: dotnet, cross-platform
- tags: -schema, csharp, typescript-codegen, yaml, schema-validation, code-generation
