Context

When scaffolding a .NET Aspire 13.1 solution with multiple services, containers, and infrastructure resources. Applies to any project using Aspire for orchestration.

Patterns

Template selection

• aspire-apphost for the orchestrator (generates AppHost.cs, not Program.cs)
• aspire-servicedefaults for shared defaults (OTel, health checks, service discovery)
• Standard webapi, worker, classlib templates for service projects — Aspire doesn't need special service templates

Container endpoints for non-HTTP services

Non-HTTP containers (Minecraft, game servers, TCP services) need explicit scheme: "tcp":
