.NET Skills is an AI coding plugin that provides skills and specialized guidance for professional .NET development, covering areas such as C#, Akka.NET, Aspire, Entity Framework Core, testing, and performance. .NET developers use it with coding assistants to apply production-oriented patterns while building and maintaining applications. The catalogue contains the plugin’s skills, agents, and instructions.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00043 | $0.01805 |
| Opus 5 | $0.00022 | $0.00903 |
| Sonnet 5 | $0.00009 | $0.00361 |
| Haiku 4.5 | $0.00004 | $0.00180 |
Grade A, and why
aspire-integration-testing 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 10d 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.

Integration Testing with .NET Aspire + xUnit
When to Use This Skill
Use this skill when:
- Writing integration tests for .NET Aspire applications
- Testing ASP.NET Core apps with real database connections
- Verifying service-to-service communication in distributed applications
- Testing with actual infrastructure (SQL Server, Redis, message queues) in containers
- Combining Playwright UI tests with Aspire-orchestrated services
- Testing microservices with proper service discovery and networking
Reference Files
- advanced-patterns.md: Endpoint discovery, database testing, Playwright, conditional config, Respawn, service communication, message queues
- ci-and-tooling.md: CI/CD integration, custom resource waiters, Aspire CLI with MCP
Core Principles
- Real Dependencies - Use actual infrastructure (databases, caches) via Aspire, not mocks
- Dynamic Port Binding - Let Aspire assign ports dynamically (
127.0.0.1:0) to avoid conflicts - Fixture Lifecycle - Use
IAsyncLifetimefor proper test fixture setup and teardown - Endpoint Discovery - Never hard-code URLs; discover endpoints from Aspire at runtime
- Parallel Isolation - Use xUnit collections to control test parallelization
- Health Checks - Always wait for services to be healthy before running tests

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

aspire-integration-testing is a skill published in the GitHub repository Aaronontheweb/dotnet-skills (1,147 stars, last pushed 1mo ago), licensed MIT. It adds 43 tokens to every session and 1,805 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 2026-08-30.
