Microsoft Agent Framework, Microsoft Foundry, MCP, Aspire를 활용한 실전 예제 만들기
AI 에이전트를 개발하는 것은 점점 쉬워지고 있습니다. 하지만 여러 서비스, 상태 관리, 프로덕션 인프라를 갖춘 실제 애플리케이션의 일부로 배포하는 것은 여전히 복잡합니다. 실제로 .NET 개발자 커뮤니티에서는 로컬 머신과 클라우드 네이티브 방식의 클라우드 환경 모두에서 실제로 동작하는 실전 예제에 대한 요구가 많았습니다. 그래서 준비했습니다! Microsoft Agent Framework과 Microsoft Foundry, MCP(Model Context Protocol), Aspire등을 어떻게 프로덕션 상황에서 조합할 수 있는지를 보여주는 오픈소스 Interview Coach 샘플입니다. AI 코치가 인성 면접 질문과 기술 면접 질문을 안내한 후, 요약을 제공하는 효율적인 면접 시뮬레이터입니다. 이 포스트에서는 어떤 패턴을 사용했고 해당 패턴이 해결할 수 있는 문제를 다룹니다. Interview Coach 데모 앱을 방문해 보세요. 왜 Microsoft Agent Framework을 써야 하나요? .NET으로 AI 에이전트를 구축해 본 적이 있다면, Semantic Kernel이나 AutoGen, 또는 두 가지 모두를 사용해 본 적이 있을 겁니다. Microsoft Agent Framework는 그 다음 단계로서, 각각의 프로젝트에서 효과적이었던 부분을 하나의 프레임워크로 통합했습니다. AutoGen의 에이전트 추상화와 Semantic Kernel의 엔터프라이즈 기능(상태 관리, 타입 안전성, 미들웨어, 텔레메트리 등)을 하나로 통합했습니다. 또한 멀티 에이전트 오케스트레이션을 위한 그래프 기반 워크플로우도 추가했습니다. 그렇다면 .NET 개발자에게 이것이 어떤 의미로 다가올까요? 하나의 프레임워크. Semantic Kernel과 AutoGen 사이에서 더 이상 고민할 필요가 없습니다. 익숙한 패턴. 에이전트는 의존성 주입, IChatClient , 그리고 ASP.NET 앱과 동일한 호스팅 모델을 사용합니다. 프로덕션을 위한 설계. OpenTelemetry, 미들웨어 파이프라인, Aspire 통합이 포함되어 있습니다. 멀티 에이전트 오케스트레이션. 순차 실행, 동시 실행, 핸드오프 패턴, 그룹 채팅 등 다양한 멀티 에이전트 오케스트레이션 패턴을 지원합니다. Interview Coach는 이 모든 것을 Hello World가 아닌 실제 애플리케이션에 적용합니다. 왜 Microsoft Foundry를 써야 하나요? AI 에이전트에는 모델 말고도 더 많은 무언가가 필요합니다. 우선 인프라가 필요하겠죠. Microsoft Foundry는 AI 애플리케이션을 구축하고 관리하기 위한 Azure 플랫폼이며, Microsoft Agent Framework의 권장 백엔드입니다. Foundry는 자체 포털에서 아래와 같은 내용을 제공합니다: 모델 액세스. OpenAI, Meta, Mistral 등의 모델 카탈로그를 하나의 엔드포인트로 제공합니다. 콘텐츠 세이프티. 에이전트가 벗어나지 않도록 기본으로 제공하는 콘텐츠 조정 및 PII 감지 기능이 있습니다. 비용 최적화 라우팅. 에이전트의 요청을 자동으로 최적의 모델로 라우팅합니다. 평가 및 파인튜닝. 에이전트 품질을 측정하고 시간이 지남에 따라 개선할 수 있습니다. 엔터프라이즈 거버넌스. Entra ID와 Microsoft Defender를 통한 ID, 액세스 제어, 규정 준수를 지원합니다. Interview Coach에서 Foundry는 에이전트를 구동하는 모델 엔드포인트를 제공합니다. 에이전트 코드가 IChatClient 인터페이스를 사용하기 때문에, Foundry는 LLM 선택을 위한 설정에 불과할 수도 있겠지만, 에이전트가 필요로 하는 가장 많은 도구를 기본적으로 제공하는 선택지입니다. Interview Coach는 무엇을 하나요? Interview Coach는 모의 면접을 진행하는 대화형 AI입니다. 이력서와 채용 공고를 제공하면, 에이전트가 나머지를 처리합니다: 접수. 이력서와 목표 직무 설명을 수집합니다. 행동 면접. 경험에 맞춘 STAR 기법 질문을 합니다. 기술 면접. 직무별 기술 질문을 합니다. 요약. 구체적인 피드백과 함께 성과 리뷰를 생성합니다. Blazor 웹 UI를 통해 실시간으로 응답 스트리밍을 제공하며 사용자와 에이전트간 상호작용합니다. 아키텍처 개요 애플리케이션은 Aspire를 통해 다양한 서비스를 오케스트레이션합니다: LLM 제공자. 다양한 모델 액세스를 위한 Microsoft Foundry (권장). WebUI. 면접 대화를 위한 Blazor 채팅 인터페이스. 에이전트. Microsoft Agent Framework로 구축된 면접 로직. MarkItDown MCP 서버. Microsoft의 MarkItDown을 통해 이력서(PDF, DOCX)를 마크다운으로 변환합니다. InterviewData MCP 서버. SQLite에 세션을 저장하는 .NET MCP 서버. Aspire가 서비스 디스커버리, 상태 확인, 텔레메트리를 처리합니다. 각 컴포넌트는 별도의 프로세스로 실행시키며, 하나의 커맨드 만으로 전체를 시작할 수 있습니다. 패턴 1: 멀티 에이전트 핸드오프 이 샘플에서 가장 흥미로운 부분이기도 한 핸드오프 패턴으로 멀티 에이전트 시나리오를 구성했습니다. 하나의 에이전트가 모든 것을 처리하는 대신, 면접은 다섯 개의 전문 에이전트로 나뉩니다: 에이전트 역할 도구 Triage 메시지를 적절한 전문가에게 라우팅 없음 (순수 라우팅) Receptionist 세션 생성, 이력서 및 채용 공고 수집 MarkItDown + InterviewData Behavioral Interviewer STAR 기법을 활용한 행동 면접 질문 진행 InterviewData Technical Interviewer 직무별 기술 질문 진행 InterviewData Summarizer 최종 면접 요약 생성 InterviewData 핸드오프 패턴에서는 하나의 에이전트가 대화의 전체 제어권을 다음 에이전트에게 넘깁니다. 그러면 넘겨 받는 에이전트가 모든 제어권을 인수합니다. 이는 주 에이전트가 다른 에이전트를 도우미로 호출하면서도 제어권을 유지하는 "agent-as-tools(도구로서의 에이전트)" 방식과는 다릅니다. 핸드오프 워크플로우를 어떻게 구성하는지 살펴보시죠: var workflow = AgentWorkflowBuilder .CreateHandoffBuilderWith(triageAgent) .WithHandoffs(triageAgent, [receptionistAgent, behaviouralAgent, technicalAgent, summariserAgent]) .WithHandoffs(receptionistAgent, [behaviouralAgent, triageAgent]) .WithHandoffs(behaviouralAgent, [technicalAgent, triageAgent]) .WithHandoffs(technicalAgent, [summariserAgent, triageAgent]) .WithHandoff(summariserAgent, triageAgent) .Build(); 면접 상황을 상상해 본다면 기본적으로 순차적인 방식으로 진행합니다: Receptionist → Behavioral → Technical → Summarizer. 각 전문가가 직접 다음으로 핸드오프합니다. 예상치 못한 상황이 발생하면, 에이전트는 재라우팅을 위해 Triage로 돌아갑니다. 이 샘플에는 더 간단한 배포를 위한 단일 에이전트 모드도 포함하고 있어, 두 가지 접근 방식을 나란히 비교할 수 있습니다. 패턴 2: 도구 통합을 위한 MCP 이 프로젝트에서 도구는 에이전트 내부에 구현하는 대신 MCP(Model Context Protocol) 서버를 통해 통합합니다. 동일한 MarkItDown 서버가 완전히 다른 에이전트 프로젝트에서도 쓰일 수 있으며, 도구 개발팀은 에이전트 개발팀과 독립적으로 배포할 수 있습니다. MCP는 또한 언어에 구애받지 않으므로, 이 샘플 앱에서 쓰인 MarkItDown은 Python 기반의 서버이고, 에이전트는 .NET 기반으로 동작합니다. 에이전트는 시작 시 MCP 클라이언트를 통해 도구를 발견하고, 적절한 에이전트에게 전달합니다: var receptionistAgent = new ChatClientAgent( chatClient: chatClient, name: "receptionist", instructions: "You are the Receptionist. Set up sessions and collect documents...", tools: [.. markitdownTools, .. interviewDataTools]); 각 에이전트는 필요한 도구만 받습니다. Triage는 도구를 받지 않고(라우팅만 수행), 면접관은 세션 액세스를, Receptionist는 문서 파싱과 세션 액세스를 받습니다. 이는 최소 권한 원칙을 따릅니다. 패턴 3: Aspire 오케스트레이션 Aspire가 모든 것을 하나로 연결합니다. 앱 호스트는 서비스 토폴로지를 정의합니다: 어떤 서비스가 존재하는지, 서로 어떻게 의존하는지, 어떤 구성을 받는지. 다음을 제공합니다: 서비스 디스커버리. 서비스가 하드코딩된 URL이 아닌 이름으로 서로를 찾습니다. 상태 확인. Aspire 대시보드에서 모든 컴포넌트의 상태를 보여줍니다. 분산 추적. 공유 서비스 기본값을 통해 OpenTelemetry가 연결됩니다. 단일 커맨드 시작. aspire run --file ./apphost.cs 로 모든 것을 시작합니다. 배포 시, azd up 으로 전체 애플리케이션을 Azure Container Apps에 푸시합니다. 시작하기 사전 요구 사항 .NET 10 SDK 이상 Azure 구독 Microsoft Foundry 프로젝트 Docker Desktop 또는 기타 컨테이너 런타임 로컬에서 실행하기 git clone https://github.com/Azure-Samples/interview-coach-agent-framework.git cd interview-coach-agent-framework # 자격 증명 구성 dotnet user-secrets --file ./apphost.cs set MicrosoftFoundry:Project:Endpoint "<your-endpoint>" dotnet user-secrets --file ./apphost.cs set MicrosoftFoundry:Project:ApiKey "<your-key>" # 모든 서비스 시작 aspire run --file ./apphost.cs Aspire 대시보드를 열고, 모든 서비스가 Running으로 표시될 때까지 기다린 후, WebUI 엔드포인트를 클릭하여 모의 면접을 시작하세요. 핸드오프 패턴이 어떻게 동작하는지 DevUI에서 시각화한 모습입니다. 이 채팅 UI를 사용하여 면접 후보자로서 에이전트와 상호작용할 수 있습니다. Azure에 배포하기 azd auth login azd up 배포를 위해서는 이게 사실상 전부입니다! Aspire와 azd 가 나머지를 처리합니다. 배포와 테스트를 완료한 후, 다음 명령어를 실행하여 모든 리소스를 안전하게 삭제할 수 있습니다: azd down --force --purge 이 샘플에서 배울 수 있는 것 Interview Coach를 통해 다음을 경험하게 됩니다: Microsoft Foundry를 모델 백엔드로 사용하기 Microsoft Agent Framework로 단일 에이전트 및 멀티 에이전트 시스템 구축하기 핸드오프 오케스트레이션으로 전문 에이전트 간 워크플로우 분할하기 에이전트 코드와 독립적으로 MCP 도구 서버 생성 및 사용하기 Aspire로 멀티 서비스 애플리케이션 오케스트레이션하기 일관되고 구조화된 동작을 생성하는 프롬프트 작성하기 azd up 으로 모든 것 배포하기 사용해 보세요 전체 소스 코드는 GitHub에 있습니다: Azure-Samples/interview-coach-agent-framework Microsoft Agent Framework가 처음이라면, 프레임워크 문서와 Hello World 샘플부터 시작하세요. 그런 다음 여기로 돌아와서 더 큰 프로젝트에서 각 부분이 어떻게 결합되는지 확인하세요. 이러한 패턴으로 무언가를 만들었다면, 이슈를 열어 알려주세요. 다음 계획 다음과 같은 통합 시나리오를 현재 작업 중입니다. 작업이 끝나는 대로 이 샘플 앱을 업데이트 하도록 하겠습니다.

AI-assisted development has grown far beyond simple code suggestions. GitHub Copilot now supports multiple AI models, each optimized for different workflows, from quick edits to deep debugging to multi-step agentic tasks that generate or modify code across your entire repository. As developers, this flexibility is powerful… but only if we know how to choose the right model at the right time. In this guide, I’ll break down: Why model selection matters The four major categories of development tasks A simplified, developer-friendly model comparison table Enterprise considerations and practical tips This is written from the perspective of real-world customer conversations, GitHub Copilot demos, and enterprise adoption journeys Why Model Selection Matters GitHub Copilot isn’t tied to a single model. Instead, it offers a range of models, each with different strengths: Some are optimized for speed Others are optimized for reasoning depth Some are built for agentic workflows Choosing the right model can dramatically improve: The quality of the output The speed of your workflow The accuracy of Copilot’s reasoning The effectiveness of Agents and Plan Mode Your usage efficiency under enterprise quotas Model selection is now a core part of modern software development, just like choosing the right library, framework, or cloud service. The Four Task Categories (and which Model Fits) To simplify model selection, I group tasks into four categories. Each category aligns naturally with specific types of models. 1. Everyday Development Tasks Examples: Writing new functions Improving readability Generating tests Creating documentation Best fit: General-purpose coding models (e.g., GPT‑4.1, GPT‑5‑mini, Claude Sonnet) These models offer the best balance between speed and quality. 2. Fast, Lightweight Edits Examples: Quick explanations JSON/YAML transformations Small refactors Regex generation Short Q&A tasks Best fit: Lightweight models (e.g., Claude Haiku 4.5) These models give near-instant responses and keep you “in flow.” 3. Complex Debugging & Deep Reasoning Examples: Analyzing unfamiliar code Debugging tricky production issues Architecture decisions Multi-step reasoning Performance analysis Best fit: Deep reasoning models (e.g., GPT‑5, GPT‑5.1, GPT‑5.2, Claude Opus) These models handle large context, produce structured reasoning, and give the most reliable insights for complex engineering tasks. 4. Multi-step Agentic Development Examples: Repo-wide refactors Migrating a codebase Scaffolding entire features Implementing multi-file plans in Agent Mode Automated workflows (Plan → Execute → Modify) Best fit: Agent-capable models (e.g., GPT‑5.1‑Codex‑Max, GPT‑5.2‑Codex) These models are ideal when you need Copilot to execute multi-step tasks across your repository. GitHub Copilot Models - Developer Friendly Comparison The set of models you can choose from depends on your Copilot subscription, and the available options may evolve over time. Each model also has its own premium request multiplier, which reflects the compute resources it requires. If you're using a paid Copilot plan, the multiplier determines how many premium requests are deducted whenever that model is used. Model Category Example Models (Premium request Multiplier for paid plans) What they’re best at When to Use Them Fast Lightweight Models Claude Haiku 4.5, Gemini 3 Flash (0.33x) Grok Code Fast 1 (0.25x) Low latency, quick responses Small edits, Q&A, simple code tasks General-Purpose Coding Models GPT‑4.1, GPT‑5‑mini (0x) GPT-5-Codex, Claude Sonnet 4.5 (1x) Reliable day‑to‑day development Writing functions, small tests, documentation Deep Reasoning Models GPT-5.1 Codex Mini (0.33x) GPT‑5, GPT‑5.1, GPT-5.1 Codex, GPT‑5.2, Claude Sonnet 4.0, Gemini 2.5 Pro, Gemini 3 Pro (1x) Claude Opus 4.5 (3x) Complex reasoning and debugging Architecture work, deep bug diagnosis Agentic / Multi-step Models GPT‑5.1‑Codex‑Max, GPT‑5.2‑Codex (1x) Planning + execution workflows Repo-wide changes, feature scaffolding Enterprise Considerations For organizations using Copilot Enterprise or Business: Admins can control which models employees can use Model selection may be restricted due to security, regulation, or data governance You may see fewer available models depending on your organization’s Copilot policies Using "Auto" Model selection in GitHub Copilot GitHub Copilot’s Auto model selection automatically chooses the best available model for your prompts, reducing the mental load of picking a model and helping you avoid rate‑limiting. When enabled, Copilot prioritizes model availability and selects from a rotating set of eligible models such as GPT‑4.1, GPT‑5 mini, GPT‑5.2‑Codex, Claude Haiku 4.5, and Claude Sonnet 4.5 while respecting your subscription level and any administrator‑imposed restrictions. Auto also excludes models blocked by policies, models with premium multipliers greater than 1, and models unavailable in your plan. For paid plans, Auto provides an additional benefit: a 10% discount on premium request multipliers when used in Copilot Chat. Overall, Auto offers a balanced, optimized experience by dynamically selecting a performant and cost‑efficient model without requiring developers to switch models manually. Read more about the 'Auto' Model selection here - About Copilot auto model selection - GitHub Docs Final Thoughts GitHub Copilot is becoming a core part of the developer workflows. Choosing the right model can dramatically improve your productivity, the accuracy of Copilot’s responses, your experience with multi-step agentic tasks, your ability to navigate complex codebases Whether you’re building features, debugging complex issues, or orchestrating repo-wide changes, picking the right model helps you get the best out of GitHub Copilot.

At a recent developer conference, I delivered a session on Legacy Code Rescue using GitHub Copilot App Modernization. Throughout the day, conversations with developers revealed a clear divide: some have fully embraced Agentic AI in their daily coding, while others remain cautious. Often, this hesitation isn't due to reluctance but stems from organizational concerns around security and regulatory compliance. Having witnessed similar patterns during past technology shifts, I understand how these barriers can slow adoption. In this blog, I'll demystify the most common security concerns about GitHub Copilot and explain how its built-in features address them, empowering organizations to confidently modernize their development workflows. GitHub Copilot Model Training A common question I received at the conference was whether GitHub uses your code as training data for GitHub Copilot. I always direct customers to the GitHub Copilot Trust Center for clarity, but the answer is straightforward: “No. GitHub uses neither Copilot Business nor Enterprise data to train the GitHub model.” Notice this restriction also applies to third-party models as well (e.g. Anthropic, Google). GitHub Copilot Intellectual Property indemnification policy A frequent concern I hear is, since GitHub Copilot’s underlying models are trained on sources that include public code, it might simply “copy and paste” code from those sources. Let’s clarify how this actually works: Does GitHub Copilot “copy/paste”? “The AI models that create Copilot’s suggestions may be trained on public code, but do not contain any code. When they generate a suggestion, they are not “copying and pasting” from any codebase.” To provide an additional layer of protection, GitHub Copilot includes a “duplicate detection filter”. This feature helps prevent suggestions that closely match public code from being surfaced. (Note: This duplicate detection currently does not apply to the Copilot coding agent.) More importantly, customers are protected by an Intellectual Property indemnification policy. This means that if you receive an unmodified suggestion from GitHub Copilot and face a copyright claim as a result, Microsoft will defend you in court. GitHub Copilot Data Retention Another frequent question I hear concerns GitHub Copilot’s data retention policies. For organizations on GitHub Copilot Business and Enterprise plans, retention practices depend on how and where the service is accessed from: Access through IDE for Chat and Code Completions: Prompts and Suggestions: Not retained. User Engagement Data: Kept for two years. Feedback Data: Stored for as long as needed for its intended purpose. Other GitHub Copilot access and use: Prompts and Suggestions: Retained for 28 days. User Engagement Data: Kept for two years. Feedback Data: Stored for as long as needed for its intended purpose. For Copilot Coding Agent, session logs are retained for the life of the account in order to provide the service. Excluding content from GitHub Copilot To prevent GitHub Copilot from indexing sensitive files, you can configure content exclusions at the repository or organization level. In VS Code, use the .copilotignore file to exclude files client-side. Note that files listed in .gitignore are not indexed by default but may still be referenced if open or explicitly referenced (unless they’re excluded through .copilotignore or content exclusions). The life cycle of a GitHub Copilot code suggestion Here are the key protections at each stage of the life cycle of a GitHub Copilot code suggestion: In the IDE: Content exclusions prevent files, folders, or patterns from being included. GitHub proxy (pre-model safety): Prompts go through a GitHub proxy hosted in Microsoft Azure for pre-inference checks: screening for toxic or inappropriate language, relevance, and hacking attempts/jailbreak-style prompts before reaching the model. Model response: With the public code filter enabled, some suggestions are suppressed. The vulnerability protection feature blocks insecure coding patterns like hardcoded credentials or SQL injections in real time. Disable access to GitHub Copilot Free Due to the varying policies associated with GitHub Copilot Free, it is crucial for organizations to ensure it is disabled both in the IDE and on GitHub.com. Since not all IDEs currently offer a built-in option to disable Copilot Free, the most reliable method to prevent both accidental and intentional access is to implement firewall rule changes, as outlined in the official documentation. Agent Mode Allow List Accidental file system deletion by Agentic AI assistants can happen. With GitHub Copilot agent mode, the "Terminal auto approve” setting in VS Code can be used to prevent this. This setting can be managed centrally using a VS Code policy. MCP registry Organizations often want to restrict access to allow only trusted MCP servers. GitHub now offers an MCP registry feature for this purpose. This feature isn’t available in all IDEs and clients yet, but it's being developed. Compliance Certifications The GitHub Copilot Trust Center page lists GitHub Copilot's broad compliance credentials, surpassing many competitors in financial, security, privacy, cloud, and industry coverage. SOC 1 Type 2: Assurance over internal controls for financial reporting. SOC 2 Type 2: In-depth report covering Security, Availability, Processing Integrity, Confidentiality, and Privacy over time. SOC 3: General-use version of SOC 2 with broad executive-level assurance. ISO/IEC 27001:2013: Certification for a formal Information Security Management System (ISMS), based on risk management controls. CSA STAR Level 2: Includes a third-party attestation combining ISO 27001 or SOC 2 with additional cloud control matrix (CCM) requirements. TISAX: Trusted Information Security Assessment Exchange, covering automotive-sector security standards. In summary, while the adoption of AI tools like GitHub Copilot in software development can raise important questions around security, privacy, and compliance, it’s clear that existing safeguards in place help address these concerns. By understanding the safeguards, configurable controls, and robust compliance certifications offered, organizations and developers alike can feel more confident in embracing GitHub Copilot to accelerate innovation while maintaining trust and peace of mind.Microsoft Foundry for VS Code: January 2026 Update
Enhanced Workflow and Agent Experience The January 2026 update for Microsoft Foundry extension in VS Code brings a follow update to the capabilities we introduced during Ignite of last year. We’re excited to announce a set of powerful updates that make building and managing AI workflows in Azure AI Foundry even more seamless. These enhancements are designed to give developers greater flexibility, visibility, and control when working with multi-agent systems and workflows. Support for Multiple Workflows in the Visualizer Managing complex AI solutions often involves multiple workflows. With this update, the Workflow Visualizer now supports viewing and navigating multiple workflows in a single project. This makes it easier to design, debug, and optimize interconnected workflows without switching contexts. View and Test Prompt Agents in the Playground Prompt agents are a critical part of orchestrating intelligent behaviors. You can now view all prompt agents directly in the Playground and test them interactively. This feature helps you validate agent logic and iterate quickly, ensuring your prompts deliver the desired outcomes. Open Code files Transparency and customization are key for developers. We’ve introduced the ability to open sample code files for all agents, including: Prompt agents YAML-based workflows Hosted agents Foundry classic agents This gives you the ability to programmatically run agents, enabling adding these agents into your existing project. Separated Resource View for v1 and v2 Agents To reduce confusion and improve clarity, we’ve introduced a separated resource view for Foundry Classic resources and agents. This makes it simple to distinguish between legacy and new-generation agents, ensuring you always know which resources you’re working with.

Happy New Year! 🎆 We are kicking off 2026 with a major set of updates designed to streamline how you build, test, and deploy AI agents. This month, we’ve focused on aligning with the latest GitHub Copilot standards, introducing powerful new debugging tools, and enhancing our support for enterprise-grade models via Microsoft Foundry. 💡 From Copilot Instructions to Agent Skills The biggest architectural shift following the latest VS Code Copilot standards, in v0.28.1 is the transition from Copilot Instructions to Copilot Skills. This transition has equipped GitHub Copilot specialized skills on developing AI agents using Microsoft Foundry and Agent Framework in a cost-efficient way. In AI Toolkit, we have migrated our Copilot Tools from the Custom Instructions to Agent Skills. This change allows for a more capable integration within GitHub Copilot Chat. 🔄 Enhanced AIAgentExpert: Our custom agent now has a deeper understanding of workflow code generation and evaluation planning/execution. 🧹Automatic Migration: When you upgrade to v0.28.1, the toolkit will automatically clean up your old instructions to ensure a seamless transition to the new skills-based framework. 🏗️ Major Enhancements to Agent Development Our v0.28.0 milestone release brought significant improvements to how agents are authored and authenticated. 🔒 Anthropic & Entra Auth Support We’ve expanded the Agent Builder and Playground to support Anthropic models using Entra Auth types. This provides enterprise developers with a more secure way to leverage Claude models within the Agent Framework while maintaining strict authentication standards. 🏢 Foundry-First Development We are prioritizing the Microsoft Foundry ecosystem to provide a more robust development experience: Foundry v2: Code generation for agents now defaults to Foundry v2. ⚡ Eval Tool: You can now generate evaluation code directly within the toolkit to create and run evaluations in Microsoft Foundry. 📊 Model Catalog: We’ve optimized the Model Catalog to prioritize Foundry models and improved general loading performance. 🏎️ 💻 Performance and Local Models For developers building on Windows, we continue to optimize the local model experience: Profiling for Windows ML: Version 0.28.0 introduces profiling features for Windows ML-based local models, allowing you to monitor performance and resource utilization directly within VS Code. Platform Optimization: To keep the interface clean, we’ve removed the Windows AI API tab from the Model Catalog when running on Linux and macOS platforms. 🐛 Squashing Bugs & Polishing the Experience Codespaces Fix: Resolved a crash occurring when selecting images in the Playground while using GitHub Codespaces. Resource Management: Fixed a delay where newly added models wouldn't immediately appear in the "My Resources" view. Claude Compatibility: Fixed an issue where non-empty content was required for Claude models when used via the AI Toolkit in GitHub Copilot. 🚀 Getting Started Ready to experience the future of AI development?
