GitHub Copilot Agent Preview, Azure AI Foundry GA, and Smarter .NET Workflows
This week, GitHub advances developer automation with the Copilot agent’s public preview, introducing actionable workflows and dashboard-driven task management that change how teams approach code generation and review at scale. Microsoft’s Azure AI Foundry simultaneously reaches general availability, bringing new tools for secure model and agent deployments—while also aligning with the expanding Model Context Protocol for multi-agent and cross-platform support. Alongside, .NET 10 lowers barriers to fast scripting and cross-device app-building, streamlining developer productivity. These moves reflect the industry’s pivot toward scalable, standardized AI, more robust cloud services, and tools that fit the realities of cross-platform, hybrid workflows.
This Week’s Overview
GitHub Copilot
This week’s GitHub Copilot updates showcase growing maturity in AI tooling for developers, spotlighting productivity improvements through advanced workflows, customizable automation, and cross-IDE feature growth. VS Code, Xcode, and other environments now offer powerful configuration avenues so teams can tune Copilot to match specific project requirements, with a focus on scalable task automation, end-to-end workflow support, community sharing, and prompt optimization for larger codebases.
Advanced Customizations and Team Alignment
New custom chat modes in Visual Studio Code, as detailed by Harald Binkle, empower developers to instantly toggle AI behaviors for reviewing code, writing tests, designing APIs, or documenting. Storing .chatmode.md
files in .github/chatmodes/
ensures precise enablement and team-wide AI behavior standardization, driving consistency on complex projects. In parallel, Microsoft introduced the ‘Awesome GitHub Copilot Customizations’ repo—making it far easier for teams to define, share, and integrate purpose-built instructions, prompts, and chat modes. Teams now centralize standards while maintaining adaptability for unique workflows, aided by practical tips to blend global and domain-specific instructions.

Cross-IDE Support and Prompt Optimization
Copilot Vision extends key features to Xcode, including image upload/discussion in chat—crucial for UI reviews in macOS development—alongside enhanced custom instructions and locale-aware support. Prompt engineering best practices are further emphasized: specificity (languages, frameworks, intent) in prompts is proving essential for quality output. Moving from generic to highly tailored prompting is accelerating accurate code generation and faster bug fixes.

AI
Recent developments highlight the growing accessibility, modularity, and social impact of AI in the .NET and Microsoft ecosystem. There’s a strong focus on developer-centric agent orchestration, cross-platform model integration, local AI workflows, and impactful applications in areas like education.
Orchestrating and Standardizing AI Agent Workflows
A new demo shows .NET developers orchestrating multiple AI agents within a Blazor app via the Semantic Kernel Agent Framework. By combining specialized agents (e.g., “Movies” and “Food” assistants) within a concurrency-managed orchestration service, developers enable scalable recommendation/chatbot behaviors. The approach aligns with broader trends—context-driven, modular, and maintainable AI—offering immediately practical blueprints.
Microsoft’s upcoming ‘MCP Dev Days’ will dive deep into the Model Context Protocol, covering live IDE integrations, secure agent server construction, and rapid onboarding. MCP’s standardization will bring uniformity, secure onboarding, and easier model swapping, benefiting both enterprise and open-source projects.
