🚀 C# .NET PoC - Marten

📖 About the Project

This repository contains a Proof of Concept (PoC) to demonstrate the use of Marten as an Event Store and ORM in .NET.

The main goal is to validate the technical feasibility of Marten within an architecture based on DDD (Domain-Driven Design), Clean Architecture, and CQRS (Command Query Responsibility Segregation).

🛠️ Technologies Used

• .NET 8
• ASP.NET Core
• Marten (Event Store & ORM)
• Docker
• PostgreSQL
• MediatR (for CQRS)
• Swagger (API documentation)
