Unity 6 – Firebase & AWS Integration (Cognito, Lambda, DynamoDB)

This repository solves a critical integration challenge for Unity 6 projects:
Unity 6 adopts .NET Framework 2.5, while the official AWS SDKs are built for .NET Framework 2.0.
This version mismatch causes runtime incompatibilities and prevents direct use of the SDK—especially affecting:

• AWS Cognito authentication
• Lambda function triggers
• DynamoDB operations

---

Solution

To bridge this gap, it was implemented custom HTTP requests using UnityWebRequest to interact directly with AWS APIs, ensuring compatibility with Unity 6’s runtime and IL2CPP builds.

All integrations are encapsulated using a modular Service Locator architecture, abstracting away complexity for developers and enabling scalable, maintainable, plug-and-play service management.
