## What it is
YamlDotNet is a YAML library for .NET runtimes including netstandard, .NET 8/10, and .NET Framework. It provides low-level YAML parsing and emitting, a high-level object model, and a serialization library for reading and writing objects to and from YAML streams.

## Use cases
- serialize C# objects to YAML
- parse YAML files in .NET
- deserialize YAML into objects
- emit YAML documents programmatically
- read configuration files written in YAML
- convert between YAML and .NET object models

## When to choose
- you need YAML support in any .NET runtime including netstandard
- you want both low-level parsing and high-level object serialization
- you need YAML 1.1 and 1.2 spec conformance
- you want a mature, widely-used MIT-licensed YAML library

## When to avoid
- you work outside the .NET ecosystem
- you need YAML 1.2 emitting, which is not yet supported
- you need a general-purpose data format library covering JSON or XML as well

## Facets
- artifact type: library
- maturity: stable
- function: serialization, parser, yaml
- domain: developer-tools, files, backend
- platform: dotnet, cross-platform
- tags: yaml-parser, yaml-emitter, netstandard, object-model, deserialization
