What is dotnet-aspire?

A development and operations guide for .NET Aspire, a .NET toolkit for running applications made of multiple services and supporting resources. It covers the application host, local orchestration, service connections, diagnostics, testing, and Azure deployment.

Use it to create or upgrade Aspire application hosts, connect projects to databases or Redis, configure shared defaults and observability, test distributed applications, add non-.NET services, and prepare deployments to Azure.

It helps coordinate several services without relying on ad-hoc startup instructions. It also addresses service discovery, health checks, OpenTelemetry (a standard for collecting traces and metrics), dashboards, upgrades, and mixed-language services.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00041	$0.02193
Opus 5	$0.00020	$0.01097
Sonnet 5	$0.00008	$0.00439
Haiku 4.5	$0.00004	$0.00219

Security

Grade A, and why

dotnet-aspire scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

.NET Aspire

Trigger On

Aspire.AppHost.Sdk, Aspire.Hosting.*, DistributedApplication.CreateBuilder, WithReference, WaitFor, AddProject, AddRedis, AddPostgres, aspire run, aspire init, aspire add, or aspire update
Aspire.Hosting.Testing, DistributedApplicationTestingBuilder, or a test harness that mixes an Aspire AppHost with WebApplicationFactory
orchestrating multiple services and resources with an AppHost for local development or cloud deployment
setting up ServiceDefaults, service discovery, OpenTelemetry, health checks, or the Aspire Dashboard
choosing between official first-party Aspire integrations and CommunityToolkit/Aspire
upgrading older 8.x or 9.x Aspire solutions to the current CLI and AppHost SDK model
wiring polyglot services into an Aspire topology, especially when Go, Java, Python, or extra dev-time tools enter the picture

Workflow

Classify the task first: new AppHost creation, existing-solution enlistment, integration wiring, testing and observability, deployment, or version upgrade.
Prefer the current Aspire toolchain. For greenfield or modernized work, use the Aspire CLI and current AppHost SDK instead of writing new guidance around the deprecated legacy workload.
Treat 13.1.x patches as servicing updates, not a new app model. Keep the Aspire CLI, Aspire.AppHost.Sdk, and closely coupled hosting or testing packages on the same patch line, then rerun the AppHost and deployment checks after aspire update.
Keep the AppHost code-first and topology-focused. Model services, resources, dependencies, endpoints, lifetimes, and parameters there; keep business logic out.
Keep ServiceDefaults narrow. It exists for telemetry, health checks, resilience, and service discovery, not shared domain models or general utility code.
Prefer official first-party Aspire integrations when they cover the requirement. Use CommunityToolkit/Aspire only when the capability gap is real: unsupported language hosts, extra dev infrastructure, or extension packages the official project does not provide.
Validate the whole distributed system, not one project in isolation. Local success means the AppHost starts cleanly, dependencies resolve through WithReference, the dashboard shows the expected resource graph, and end-to-end tests can exercise the topology.
For integration tests, keep one shared AppHost fixture per test session. Use Aspire.Hosting.Testing to boot the distributed app, create HttpClient or SignalR clients from the AppHost, and layer WebApplicationFactory on top only when tests need direct Host DI, grains, or runtime services.
When publishing, switch from local containers or emulators to managed resources deliberately and verify which services truly need external endpoints.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dotnet-aspire is a skill published in the GitHub repository Postpartum-genushyacinthus29/dotnet-skills (10 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 2,193 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
