OnionForge AI — Enterprise Architecture Generator for .NET

OnionForge AI is a next-generation Visual Studio extension and CLI toolkit designed to accelerate enterprise-grade .NET development using modern architectural patterns.

Built specifically for developers and software architects, OnionForge automates the creation of production-ready code using:

Onion Architecture Domain-Driven Design (DDD) CQRS MediatR FluentValidation Minimal APIs Clean Architecture principles Repository + Unit of Work Outbox Pattern OpenTelemetry-ready structure Docker-ready infrastructure AI-powered focused code generation 🚀 Why OnionForge?

Modern enterprise applications require a massive amount of repetitive setup and boilerplate.

OnionForge eliminates that friction by generating:

Aggregates Commands Queries Handlers Validators Minimal API endpoints Repositories EF Core configurations Docker support Outbox infrastructure Telemetry scaffolding Test-ready architecture

This allows teams to focus on business logic instead of repetitive plumbing.

✨ Key Features 🧠 AI-Powered Code Generation

Generate focused, architecture-compliant C# code using AI.

Example:

onionforge ai-code
--name CreateOrder
--module Orders
--kind command
--prompt "Create order with inventory validation and domain events"

AI generates:

Production-ready CQRS code Proper layering Validation rules DDD-friendly structures Compile-focused output 🏛 Onion Architecture + DDD

Generate enterprise-ready solutions with proper separation of concerns.

Structure includes:
