## What it is
A .NET implementation of the GraphQL query language, providing a lexer/parser, schema definition, and execution engine for building GraphQL APIs. It is distributed as NuGet packages usable from any .NET application.

## Use cases
- build a graphql api in .net
- serve graphql queries from asp.net core
- define and execute graphql schemas in c#
- add a graphql endpoint to an existing dotnet service
- parse and validate graphql queries

## When to choose
- you are building a GraphQL server or client in .NET/C#
- you need a spec-compliant GraphQL execution engine with fine-grained control
- you want a mature, MIT-licensed GraphQL library for dotnet-core

## When to avoid
- you want a batteries-included framework with opinionated conventions like Hot Chocolate
- your project is not on the .NET platform
- you only need a simple REST API without graph-style queries

## Facets
- artifact type: library
- maturity: active
- function: graphql, api-framework, parser, http-server
- domain: web-development, backend, apis, developer-tools
- platform: dotnet, cross-platform
- tags: graphql-server, query-language, execution-engine, dotnet-core, schema, web-server
