Selects a .NET UI framework. Decision tree across Blazor, MAUI, Uno, WinUI, WPF, WinForms.
Use this skill when users ask how to build Syncfusion PivotView/pivot tables in ASP.NET Core apps. Trigger for server integration, data binding (API/DB/remote), OLAP, aggregation, drill-down, grouping, filtering, conditional formatting, exporting (Excel/PDF/CSV), or pivot charts in ASP.NET Core. Not for MVC/Blazor/JS.
Use this skill when users ask how to build or customize Syncfusion PivotView pivot tables in Angular. Trigger for Angular pivot grid/OLAP, aggregation, data binding (JSON/remote), drill-down/drill-through, grouping, filtering, conditional formatting, exports (Excel/PDF/CSV), or pivot charts. Angular-only, not React/Vue/Blazor.
Guidance for embedding web content in .NET MAUI apps using HybridWebView, including JavaScript–C# interop, bidirectional communication, raw messaging, and trimming/NativeAOT considerations. USE FOR: "HybridWebView", "JavaScript interop", "embed web content", "JS to C# interop", "C# to JavaScript", "web view interop", "raw message", "InvokeJavaScriptAsync", "web content MAUI". DO NOT USE FOR: deep linking from external URLs (use maui-deep-linking), REST API calls (use maui-rest-api), or Blazor Hybrid apps (different from HybridWebView).
Detects .NET intent for any C#, ASP.NET Core, EF Core, Blazor, MAUI, Uno Platform, WPF, WinUI, SignalR, gRPC, xUnit, NuGet, or MSBuild request from prompt keywords and repository signals (.sln, .csproj, global.json, .cs files). First skill to invoke for all .NET work — loads version-specific coding standards and routes to domain skills via [skill:dotnet-advisor] before any planning or implementation. Do not use for clearly non-.NET tasks (Python, JavaScript, Go, Rust, Java).
Use this skill when users ask how to build or customize Syncfusion PivotView pivot tables in React. Trigger for React pivot grid/OLAP, aggregation, data binding (JSON/remote), drill-down/drill-through, grouping, filtering, conditional formatting, exports (Excel/PDF/CSV), or pivot charts.

USE WHEN: user works with "C#", ".NET", "ASP.NET Core", "Entity Framework", asks about ".NET vulnerabilities", "NuGet security", ".NET authentication", "Blazor security" DO NOT USE FOR: general OWASP concepts - use `owasp` or `owasp-top-10` instead, Java/Python security - use language-specific skills
Use when working with C#, F#, .NET libraries, ASP.NET Core, Blazor, Entity Framework Core, and the broader .NET ecosystem. USE FOR: .NET language features, choosing libraries and frameworks, project structure, package selection, architecture decisions DO NOT USE FOR: specific library configuration details (use the sub-skills: web, data, testing, eventing, cloud, etc.)
ASP.NET Core cross-platform .NET framework with Blazor support. Use for C# web apps.
Guides creation and modification of ASP.NET Core Web API endpoints with correct HTTP semantics, OpenAPI metadata, and error handling. USE FOR: adding new API endpoints (controllers or minimal APIs), wiring up OpenAPI/Swagger, creating .http test files, setting up global error handling middleware. DO NOT USE FOR: general C# coding style, EF Core data access or query optimization (use optimizing-ef-core-queries), frontend/Blazor work, gRPC services, or SignalR hubs.
