Build, review, refactor, or architect ASP.NET Core web applications using current official guidance for .NET web development. Use when working on Blazor Web Apps, Razor Pages, MVC, Minimal APIs, controller-based Web APIs, SignalR, gRPC, middleware, dependency injection, configuration, authentication, authorization, testing, performance, deployment, or ASP.NET Core upgrades.

Reference Sections

Use this file as the routing table for the rest of the skill.

Start Here

  • New app or major redesign: stack-selection.md -> program-and-pipeline.md -> one primary app-model reference -> security-and-identity.md -> testing-performance-and-operations.md
  • Existing app feature work: primary app-model reference -> program-and-pipeline.md -> any needed cross-cutting references
  • API-first work: apis-minimal-and-controllers.md -> security-and-identity.md -> data-state-and-services.md -> testing-performance-and-operations.md
  • Authentication, authorization, or secrets: security-and-identity.md
  • Realtime, streaming, or background processing: realtime-grpc-and-background-work.md
  • Upgrade or migration work: versioning-and-upgrades.md

Primary References

File Open when
stack-selection.md Choose Blazor, Razor Pages, MVC, Minimal APIs, controllers, SignalR, or gRPC
program-and-pipeline.md Structure Program.cs, services, configuration, middleware, routing, logging, static files, and app startup
ui-blazor.md Build or review Blazor Web Apps and component-based UI
ui-razor-pages.md Build or review page-focused server-rendered applications
ui-mvc.md Build or review controller/view applications
apis-minimal-and-controllers.md Build or review HTTP APIs

Cross-Cutting References

File Open when
data-state-and-services.md Register services, use EF Core, handle options/configuration, or manage app state
security-and-identity.md Add Identity, cookies, bearer auth, policies, CORS, CSRF, HTTPS, or secrets handling
realtime-grpc-and-background-work.md Add SignalR, gRPC, streaming, or hosted services
testing-performance-and-operations.md Add tests, caching, compression, health checks, rate limits, deployment, or proxy configuration
versioning-and-upgrades.md Migrate across ASP.NET Core versions, avoid obsolete APIs, or target preview features deliberately
source-map.md Map a task to the official ASP.NET Core documentation tree

Reading Strategy

  • Open one app-model reference at a time unless the codebase genuinely mixes models.
  • Prefer the framework's built-in abstractions first.
  • Check versioning-and-upgrades.md before introducing APIs that might not exist in the repository's target framework.

What it does

Instructs Claude on ASP.NET Core application models (Blazor Web Apps, Razor Pages, MVC, Minimal APIs), host and pipeline setup, dependency injection, configuration, authentication, testing, and deployment using current Microsoft documentation. Use for building or refactoring .NET web applications and deciding between framework patterns.

Generated from the current SKILL.md.

Frequently asked

Does this skill cover Blazor, Razor Pages, MVC, and Minimal APIs?
Yes. The skill includes dedicated references for each application model (Blazor Web Apps, Razor Pages, MVC, and Minimal/controller-based APIs) and guides you to load only the one you need for your task.
What .NET versions does this skill target?
The skill defaults to .NET 10 / ASP.NET Core 10 for new production work as of March 2026, but adapts to older pinned versions and handles migrations between major versions via the versioning-and-upgrades reference.
Does this skill use third-party libraries or stick to built-in ASP.NET Core features?
The skill prefers built-in features (DI, options, logging, ProblemDetails, OpenAPI, health checks, rate limiting, Identity) before introducing third-party infrastructure.
Can this skill help with authentication, authorization, and data access?
Yes. Cross-cutting references cover security/identity, EF Core, DbContext, and state management, loaded on-demand based on your specific task.
Does this skill guide upgrades from older ASP.NET Core versions?
Yes. The versioning-and-upgrades reference specifically handles breaking changes, obsolete APIs, and migrations between major versions.
