Skill UI

This skill specializes in building robust, scalable, and cloud-native backend microservices using the latest .NET 8 and C# 12 features. It masters modern architectural patterns, including Clean Architecture, CQRS with MediatR, and minimal APIs. Expertise covers secure authentication (JWT), data persistence with Entity Framework Core, asynchronous programming best practices, and comprehensive unit/integration testing, ensuring highly maintainable and performant code.

This SDK provides comprehensive tools for developing enterprise-grade, multi-channel agents for the Microsoft 365 ecosystem. Utilizing ASP.NET Core hosting, it supports integration with Teams, Copilot Studio, and general M365 services. Key features include robust agent application routing, structured state management, and secure authentication using MSAL.

This SDK provides Azure Functions extensions for handling Microsoft Entra ID custom authentication events within a .NET environment. Developers can intercept key stages of the authentication lifecycle, such as token issuance, attribute collection, and OTP sending. Use cases include enriching access tokens with custom claims, fetching external user data to populate profiles, and customizing the sign-up user experience.

Guide to spotting serialized payloads (cookies, APIs, ViewState) and weaponizing Java, PHP, Python, and .NET gadget chains to prove remote code execution during authorized penetration tests.

Extract embedded Agent Tesla RAT configuration such as SMTP/FTP/Telegram exfiltration credentials, keylogger settings, and C2 data from .NET assemblies via dnSpy/ILSpy decompilation and memory analysis for malware research or red-team validation.

Patterns for building reliable C#/.NET test suites using xUnit, FluentAssertions, mocking libraries, Testcontainers, and WebApplicationFactory so unit and integration tests stay organized and maintainable.

Guides idiomatic C# and .NET patterns covering immutability, explicit intent, dependency injection, async usage, configuration binding, result handling, and repository abstractions to build robust, maintainable applications.

Checks Microsoft SDK code by verifying API signatures, fetching docs, and finding Azure samples before writing or reviewing code that touches .NET or Microsoft APIs.

Query authoritative Microsoft documentation to explain Azure, .NET, M365, Windows, and Power Platform concepts, tutorials, limits, configurations, or best practices whenever a user wants to understand how something works.

Guides agents through researching Microsoft technologies via Learn MCP docs, then scaffolds hybrid skills that store essential knowledge locally while enabling dynamic lookups for depth.

This guide teaches how to build well-structured and robust ASP.NET Minimal APIs. It covers best practices for API organization, defining clear DTOs with proper validation, handling strongly-typed parameters, and leveraging modern C# features. Crucially, it demonstrates how to generate comprehensive, standards-compliant OpenAPI/Swagger documentation using built-in .NET features, ensuring APIs are fully documented for seamless consumption.

This comprehensive template and guide facilitate the containerization of ASP.NET Core applications. It provides a structured prompt and checklist to ensure that the resulting Dockerfile adheres to industry best practices for performance, security, and maintainability when running on Linux containers. It covers all necessary aspects, including dependency management, port exposure, build stages, and custom configuration.
