ModularVerticalSlice.NET v1.0.0

ModularVerticalSlice.NET is a modular monolith reference architecture and starter kit for .NET teams that want explicit boundaries today and a credible path toward service extraction later, without microservice overhead.

This is the first public release.

Highlights

• Evolved Vertical Slice Architecture with explicit business modules (Modules/) and delivery boundaries (Delivery/).
• Wolverine + PostgreSQL durable messaging: transactional outbox/inbox, retry, circuit breaker, sagas, scheduled messages, and dead-letter queue — no external broker required.
• DbContextSlice persistence isolation: handlers see only the tables their slice declares, with no global AppDbContext dependency.
• Architecture tests as guardrails (NetArchTest): module boundaries, handler and saga placement, persistence access — violations fail the build.
• Operational baseline: /health/live and /health/ready, X-Correlation-Id propagation across HTTP and message handlers, structured workflow logs, and OpenTelemetry tracing.
• Reproducible verification: ./scripts/verify.ps1 builds and runs unit, architecture, and integration tests against a disposable PostgreSQL.
• Sample domain: Event Ticket Booking (catalog, bookings, payments, confirmation delivery) demonstrating reservation, idempotency, saga timeout/compensation, and retry/DLQ behavior.

Requirements

• .NET 10 SDK
• Docker (for the disposable PostgreSQL instance)
