Securing Sensitive Mobile Operations with Device-Bound Request Signing
Mobile security goes beyond verifying user identity. If an attacker steals a valid token, how will your backend distinguish a legitimate request from one reproduced in an emulator or cloned environment? This is a gap in traditional authentication flows when applied to the mobile environment. By linking each request to hardware-backed keys generated during secure device registration, it's possible to strengthen the chain of trust and reduce the possibilities of external attacks on the device. In this blog post, we show how a device-bound, proof-of-possession-based signature mechanism can offer more robust pr...
Join the OSS AI Summit: Building with LangChain Event
December 10, 2025 8 am - 10 am Pacific Registration: https://aka.ms/OSSAISummitRegistration Overview AI development is moving at a pace that leaves most teams reacting instead of leading. The next generation of applications will be built by people who understand how to design agents, coordinate tools, and create workflows that can handle real complexity. The OSS AI Summit is designed to help you get ahead of that shift. This event focuses on LangChain v1, Microsoft Foundry, and the systems that make modern AI applications reliable, scalable, and practical to ship. If you want to build smarter agents and u...
Manage Containers the Easy Way: Copilot + VS Code
Managing containers can be one of the most repetitive parts of modern development. Between remembering CLI commands, switching contexts, and digging through logs, it’s easy to lose focus on the actual code you’re building. The latest release of the VS Code Container Tools extension changes that by putting Copilot directly into your workflow - so you can manage containers conversationally, without breaking stride. Why This Matters Containers are everywhere: local dev environments, cloud deployments, CI/CD pipelines. But the tooling often feels fragmented. This update brings a unified, intuitive way to interact w...
New developer resource page for Microsoft 365 interoperability and data portability
Microsoft has long provided interoperability information, interfaces, and tools to help our vibrant ecosystem of partners integrate their products and services with Microsoft 365 productivity applications. This ecosystem includes communication and collaboration solution providers that compete with Microsoft Teams. Alongside these resources, we have also offered data portability solutions to our customers to allow them to move between services as they see fit. Microsoft’s recent agreement with the European Commission formalizes these values into legal commitments. To meet these commitments and help developers...
Behind the Universe demo: From prompt to production with VS Code, GitHub Copilot and the Microsoft Agent Framework
At this year’s GitHub Universe, we set out to answer a simple question: What would it take to go from an idea to production in under 30 minutes – using only natural language, your editor, and AI? On stage, we built a cloud-native, intelligent app from scratch using Visual Studio Code, GitHub Copilot, and the Microsoft Agent Framework. In this post, we’ll walk through the journey step-by-step: From spec to code Modern greenfield apps aren’t just “hosted in the cloud” anymore – they’re born there. They’re expected to be cloud-native and auto-scaling. The table stakes have been raised, and t...
Put your AI to the Test with Microsoft.Extensions.AI.Evaluation
AI is changing how we build software, but it also introduces new challenges: how do you know if your AI application is giving the right answers and producing the right outcomes? Evaluations (often referred to simply as ‘evals’) provide a structured way to measure quality so you can trust your results. In this blog, we’ll introduce the concept of AI evals, show how the Microsoft.Extensions.AI.Evaluation libraries support .NET intelligent app development in Visual Studio, and walk through a simple example of how to use them in your project. Why Evaluate? As developers, we rely on tests to validate our code bef...
Complete Beginner’s Guide to Vibe Coding an App in 5 Minutes
How I built a full-featured podcast analytics dashboard with GitHub Copilot without writing a single line of code myself.
TypeScript 7 native preview in Visual Studio 2026
In March of this year Anders Hejlsberg announced TypeScript 7 native preview and in May Daniel posted Announcing TypeScript Native Previews. Visual Studio 2026 Insiders now supports TypeScript’s Native Preview. Use the download link below to install the latest preview of Visual Studio to try this out. When using this new preview, your compile times should be significantly faster, the IDE will use less memory, and you should see improved performance all around. This is especially true if you work with large TypeScript projects. What is TypeScript 7 native preview? TypeScript 7 native preview is a new version...
Visual Studio 2026 Insiders: Using Podman for Container Development
Podman is an open-source container engine that has rapidly gained popularity for its daemonless architecture, rootless operation, and compatibility with Docker CLI commands. Unlike Docker, Podman does not require a central daemon, offering improved security and flexibility - especially in enterprise and cloud-native environments. Its ability to run containers without elevated privileges makes it an attractive choice for developers focused on security and compliance. Podman Integration The integration of Podman in Visual Studio 2026 Insiders is a game-changer for developers who prefer or require Podman for their...
