Architecture

Clean Architecture .NET 9

RIVORA Framework follows a strict layered architecture with 47 projects:

Presentation (API)           Controllers, Minimal APIs, gRPC, SignalR, GraphQL
       |
Application (CQRS)          Commands, Queries, Validators, DTOs (MediatR)
       |
Domain (Business)            Entities, Value Objects, Domain Events, Specifications
       |
Infrastructure (Data)       EF Core 9, Repositories, External Services

Fundamental rule: dependencies always point inward. Domain depends on nothing. Infrastructure depends on Domain and Application, never the reverse.

Project Structure

Layer	Projects	Role
Core	Core, Domain	Abstractions, entities, events, specifications
Application	Application	CQRS (MediatR), services, validators, DTOs
Infrastructure	Infrastructure, Data.* (4 providers)	EF Core, repositories, external services
Presentation	Api, GraphQL, Admin, RealTime	REST, GraphQL, Blazor, SignalR
Security	Security, Identity.Pro	JWT, BCrypt, 2FA, Rate Limiting, Audit
Multi-Tenancy	MultiTenancy, SaaS	Tenant isolation, billing
Cross-Cutting	Caching, Jobs.*, HealthChecks, Notifications, Storage	Cross-cutting modules
AI	AI, NaturalQuery	RAG, vector store, NL Query Builder
Integration	Export, Webhooks, Client	PDF/Excel/CSV, SaaS webhooks, typed API client
DevOps	AppHost, ServiceDefaults	.NET Aspire orchestration
Tools	RVR.CLI, RVR.Studio	CLI scaffolding + AI, visual IDE

Modularity

Each module implements IRvrModule for standardized registration:

builder.Services.AddRvrModule<CachingModule>(builder.Configuration);
builder.Services.AddRvrModule<SecurityModule>(builder.Configuration);
builder.Services.AddRvrModule<MultiTenancyModule>(builder.Configuration);

This approach allows scaling from a modular monolith to microservices without major refactoring.
