SSWConsulting/SSW.VerticalSliceArchitecture

This system is a .NET 10 template implementing Vertical Slice Architecture, designed to demonstrate modern backend development patterns using FastEndpoints and .NET Aspire. It provides a structured foundation for building domain-driven APIs with features like event-driven consistency, robust pagination, and centralized observability. The project includes comprehensive tooling for local development, testing, and dependency management, serving as a reference implementation for scalable service design.

The src/ServiceDefaults/Extensions.cs file now provides a centralized configuration for .NET Aspire services. This includes automatic setup for OpenTelemetry (logging, metrics, and tracing with OTLP export), default health checks (liveness and readiness endpoints), service discovery, and HTTP client resilience. These defaults are applied via the AddServiceDefaults extension method, simplifying the integration of standard infrastructure concerns across service projects.

This entry introduces the foundational structure of the SSW Vertical Slice Architecture template, targeting .NET 10. It establishes the solution layout using the new .slnx format, defines coding standards via a comprehensive .editorconfig, and sets up the project configuration in Directory.Build.props. The template includes a sample domain (Heroes) to demonstrate Vertical Slice Architecture principles, integrates Aspire for local orchestration and observability, and provides agent skills for scaffolding new slices and entities.

The tools area now includes a new AppHost project that orchestrates the application using .NET Aspire. This setup configures an Azure App Service environment (B1 tier) for publishing and runs a local SQL Server 2025 container for development, grouped under the 'SSW-VSA' project in Docker UIs. The AppHost manages EF Core migrations via Aspire's AddEFMigrations and conditionally adds a Seeder service in run mode to populate the database with sample data using Bogus, ensuring no seed data reaches production. It also configures Application Insights and Log Analytics only in publish mode, while using the Aspire Dashboard locally.

The WebApi layer has been restructured to follow a vertical slice and domain-driven design, replacing the previous implementation with FastEndpoints. This change introduces a robust domain model for Heroes and Teams, featuring strongly typed IDs, aggregate roots, and value objects. It adds a standardized pagination and sorting system that enforces safe, allow-listed column mapping and clamped page sizes. Additionally, the API now supports eventual consistency by automatically dispatching domain events after database saves, with a middleware layer to handle offline event processing.

src/WebApi · high confidence

The Teams feature area has been re-implemented using the FastEndpoints framework, replacing the previous minimal API approach. This change introduces new endpoints for creating teams, retrieving team details (including nested hero and power data), listing teams with pagination and sorting, adding heroes to teams, and executing or completing missions. The GetAllTeams endpoint now supports standard paged envelopes with configurable page size and sort columns. Additionally, an event handler has been added to asynchronously recalculate team power levels when individual hero power levels are updated, ensuring eventual consistency across the system.

src/WebApi/Features/Teams · high confidence

Added architecture and pagination unit tests; Added integration test infrastructure and helpers; Added integration tests for Heroes and Teams endpoints; Added unit tests for Heroes and Teams domain logic and request validators.

The project now uses central package version management via Directory.Packages.props to standardize all NuGet references across the solution. This update includes upgrading core libraries such as Aspire to 13.5.3, FastEndpoints to 8.2.0, and xunit to v3.2.1, while also pinning specific transitive dependencies—MessagePack (2.5.302), Microsoft.OpenApi (2.9.0), and SSH.NET (2026.0.0)—to resolve high-severity security vulnerabilities (NU1903) and build warnings.
