## AI overview

Apollo announces an official open-source Apollo Federation support library for Hot Chocolate, a .NET GraphQL framework. The v1.0 library includes full Federation 2 support, including field migrations, entity interfaces, and more flexible type ownership.

## Source excerpt

Apollo Federation is an open specification for exposing API services as a single GraphQL access layer, known as a supergraph. In a supergraph, you connect and curate your services through smaller, modular graphs called subgraphs. There's a vibrant ecosystem of community-led frameworks that let you write subgraphs in every common language, bolstered by official Apollo Federation support libraries for JavaScript and Java.
