Establish build performance baselines and apply systematic optimization techniques. Only activate in MSBuild/.NET build context. Use when diagnosing slow builds, establishing before/after measurements, or applying advanced optimization strategies like MSBuild Server, static graph builds, artifacts output, and dependency graph trimming. Start here before diving into specific optimizations from build-perf-diagnostics, incremental-build, or build-parallelism skills. DO NOT use for non-MSBuild build systems.
Guide for modernizing and migrating MSBuild project files to SDK-style format. Only activate in MSBuild/.NET build context. Use when encountering legacy .csproj/.vbproj files with verbose XML, packages.config, or AssemblyInfo.cs patterns. Covers legacy-to-SDK migration, removing boilerplate, PackageReference migration, and Directory.Build consolidation. Invoke when asked to modernize, migrate, or clean up project files.
Create, read, edit, secure, sign, and convert PDF documents (.pdf) using Syncfusion PDF Library for .NET. Use this skill for PDF processing and document automation when the user asks to generate PDF files, modify PDF content, add security or signatures, extract text or images, merge or split PDFs, or perform PDF/A conversion using C# code or CSX execution.
Guides implementation of the Syncfusion WinForms AutoLabel control for automatic label positioning with form controls. Use when users want to add labels that automatically reposition when controls move, create form layouts with paired label-control units, implement complex form designs with FlowLayout, or ensure labels stay synchronized with their associated controls. Covers labeling controls, positioning, spacing, size settings, theming, and events.
Guide to implementing the Syncfusion Windows Forms TabbedMDIManager control for creating professional tabbed document interfaces with multiple tab groups, complete customization, event handling, and serialization support. Use this skill when users need to build MDI applications with tabbed windows, tab alignment, tab groups, button controls, appearance customization, themes, and interactive features like tooltips and context menus.
Implement Syncfusion Windows Forms Diagram control for creating interactive diagramming applications. Use this when creating flowcharts, organizational charts, network diagrams, or node-based visualizations. The control provides drag-and-drop editing, symbol palettes, connector management, and diagram serialization for building Visio-like applications in Windows Forms.
Implementing FlowLayout in Windows Forms to automatically arrange child components horizontally or vertically. Use this when working with automatic control layouts, responsive form designs, or dynamic control arrangement. Covers spacing configuration, alignment modes, control constraints, and layout positioning.
Guide for implementing Syncfusion WizardControl component in Windows Forms applications. Use when creating multi-step forms, installation wizards, setup dialogs, or step-by-step workflow interfaces with navigation buttons. Covers assembly deployment, page management, banner configuration, validation, navigation button handling, events, and appearance customization for professional wizard interfaces.
Implement and configure the Syncfusion DomainUpdownExt control in Windows Forms applications. Use this skill when you need to create dropdown/selection controls with spin buttons, customize appearance, manage items, and enable keyboard navigation in WinForms projects.
Dependency injection patterns and best practices using Microsoft.Extensions.DependencyInjection for .NET applications. Use when configuring DI containers in .NET, choosing between service lifetimes (Singleton, Scoped, Transient), or implementing decorator patterns and service interception.
Scan C# source files for hard-to-test static dependencies — DateTime.Now/UtcNow, File.*, Directory.*, Environment.*, HttpClient, Console.*, Process.*, and other untestable statics. Produces a ranked report of static call sites by frequency. USE FOR: find untestable statics, scan for static dependencies, testability audit, identify hard-to-mock code, find DateTime.Now usage, detect static coupling, testability report, static analysis for testability. DO NOT USE FOR: generating wrappers (use generate-testability-wrappers), migrating code (use migrate-static-to-wrapper), general code review, or finding statics that are already behind abstractions.
