Manages .NET project setup, build systems, and developer tooling including solution structure, MSBuild (authoring, tasks, Directory.Build), build optimization, performance patterns, profiling (dotnet-counters/trace/dump), Native AOT publishing, trimming, GC/memory tuning, CLI app architecture (System.CommandLine, Spectre.Console, Terminal.Gui), docs generation, tool management, version detection/upgrade, and solution navigation.
Guide developers through capturing diagnostic artifacts to diagnose production .NET performance issues. Use when the user needs help choosing diagnostic tools, collecting performance data, or understanding tool trade-offs across different environments (Windows/Linux, .NET Framework/modern .NET, container/non-container).
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.
Use the open-source free `coverlet` toolchain for .NET code coverage. Use when a repo needs line and branch coverage, collector versus MSBuild driver selection, or CI-safe coverage commands.
Implement or review SignalR hubs, streaming, reconnection, transport, and real-time delivery patterns in ASP.NET Core applications.
Use the free official JetBrains ReSharper Command Line Tools for .NET repositories. Use when a repo wants powerful `jb inspectcode` inspections, `jb cleanupcode` cleanup profiles, solution-level `.DotSettings` enforcement, or a stronger CLI quality gate for C# than the default SDK analyzers alone.
Generates .NET/C# SDKs from OpenAPI specifications using the AutoSDK CLI tool (autosdk.cli). Use when the user wants to create a C# client library from an OpenAPI/Swagger spec, scaffold a new SDK project, regenerate existing SDK code, or customize generated .NET API clients.
.NET and ASP.NET Core security patterns. Covers Identity, authentication, dependency auditing, secure coding practices, and OWASP for .NET ecosystem. 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
Validates custom dotnet new templates for correctness before publishing. Catches missing fields, parameter bugs, shortName conflicts, constraint issues, and common authoring mistakes that cause templates to fail silently. USE FOR: checking template.json files for errors before publishing or testing, diagnosing why a template doesn't appear after installation, reviewing template parameter definitions for type mismatches and missing defaults, finding shortName conflicts with dotnet CLI commands, validating post-action and constraint configuration. DO NOT USE FOR: finding or using existing templates (use template-discovery), creating projects from templates (use template-instantiation), creating templates from existing projects (use template-authoring).
Azure Event Grid SDK for .NET. Client library for publishing and consuming events with Azure Event Grid. Use for event-driven architectures, pub/sub messaging, CloudEvents, and EventGridEvents. Triggers: "Event Grid", "EventGridPublisherClient", "CloudEvent", "EventGridEvent", "publish events .NET", "event-driven", "pub/sub".
Manage NuGet packages using Central Package Management (CPM) and dotnet CLI commands. Never edit XML directly - use dotnet add/remove/list commands. Use shared version variables for related packages.
Diagnose and fix .NET HTTPS dev certificate trust issues on Linux. Covers the full certificate lifecycle from generation to system CA bundle inclusion, with distro-specific guidance for Ubuntu, Fedora, Arch, and WSL2.
