ASP.NET Framework Frontend

Overview

Use this skill for ASP.NET Framework frontend architecture and implementation. Keep framework-specific code guidance in sync with official Microsoft Learn documentation before giving final recommendations.

Core Workflow

1. Identify stack and runtime.

• Confirm ASP.NET Framework (MVC 5, Web API 2, Web Forms, System.Web) versus ASP.NET Core.
• Detect target runtime from .csproj, packages.config, or web.config.
• State assumptions when the runtime is unknown.

2. Choose frontend strategy.

• Choose Vue 2 for legacy maintenance and Options API continuity.
• Choose Vue 3 for new/expanded client-side features and composables.
• Choose Alpine.js for lightweight progressive enhancement in server-rendered pages.
• Use Vue + Alpine only with strict root-element isolation.
