Announcing official Apollo Federation support for .NET with Hot Chocolate and Federation 2!
Blog post from Apollo
The official Apollo Federation support library for Hot Chocolate, a popular .NET GraphQL framework, has been released with full Federation 2 support. This allows developers to create subgraphs that expose API services as a single GraphQL access layer, enabling modular and scalable architecture. The new library provides annotation-based Federation for clean idiomatic C# code, GitHub actions configured for CI/CD using GraphOS schema checks and publishing, and one-click deploy templates with Railway. It also includes comprehensive support for field migrations, entity interfaces, and flexible type ownership. With this release, Apollo continues to maintain official Federation subgraph support for Hot Chocolate, planning ongoing improvements and fixes, as well as full support for the latest Apollo Federation spec changes.
