Demo Application

API-first ASP.NET Core solution targeting .NET 10.

Architecture

• DemoApplication.Api owns HTTP endpoints, middleware, health checks, and static SPA hosting.
• DemoApplication.Application owns use-case contracts and application orchestration.
• DemoApplication.Domain owns business entities and rules; it has no framework dependencies.
• DemoApplication.Infrastructure owns external integrations and implements Application abstractions.

Dependencies point inward: API references Application and Infrastructure; Infrastructure references Application and Domain; Application references Domain.

Run

From the repository root on Windows, Linux, or macOS:

dotnet restore src/DemoApplication.slnx
dotnet run --project src/DemoApplication.Api

The API listens on the URL printed by the host. Verify startup with GET /health and GET /api/status.
