.NET Framework 3.5 Moves to Standalone Deployment in Future Windows Versions

Microsoft is changing how legacy components are delivered in upcoming Windows releases, signaling a gradual shift in platform maintenance strategy. The update affects a long-standing dependency still used by many older enterprise applications and reflects broader lifecycle planning across the Windows and .NET ecosystem. Developers and IT teams are now being encouraged to prepare for modernization as the platform evolves.

Here’s what you need to know:

• What’s changing?

  Starting with Windows 11 Insider Preview Build 27965, .NET Framework 3.5 will no longer be included as an optional Windows feature. Instead, it must be installed separately using a standalone installer.

• Who is affected?

  The change applies to new Windows platform releases moving forward. It does not impact Windows 10 or existing Windows 11 releases up to 25H2.

• Why the shift?

  With .NET Framework 3.5 reaching end of support on January 9, 2029, Microsoft is encouraging organizations to start planning migrations to supported .NET versions.

• What should you do?

  If your application depends on .NET Framework 3.5, Microsoft has published detailed guidance — including installers, compatibility notes, and recommended migration paths.

Microsoft Reveals February AI Roadmap for Visual Studio

Microsoft has shared its latest look ahead at how artificial intelligence will evolve inside Visual Studio. The February roadmap signals a shift toward stabilizing AI workflows while continuing to expand the role of agents in everyday development. The update hints at deeper integration and smarter interactions across the IDE experience.

Here’s what developers like you can expect:

• Agent Mode & Coding Agents

  Improved progress indicators for long-running tasks, smarter failure handling and retries, plus enhanced diagnostics and logging — helping agents recover gracefully and making issues easier to troubleshoot.

• Planning Agent

  A new dedicated experience designed for scoping, refining, and iterating tasks before execution — moving beyond the lightweight planning mode developers use today.

• Copilot SDK & Platform Integration

  Early work begins to integrate the Copilot CLI directly into Visual Studio Copilot for a more connected development workflow.

• Model Context Protocol (MCP)

  Continued investment in secure and scalable tool connectivity, including Client ID metadata documents and governance support for MCP servers inside Visual Studio.

• Models & Context Management

  Under-the-hood improvements to keep Copilot fast even with large contexts — simplifying context reduction and preventing unexpected behavior.

• Copilot Experience in the Editor

  Smoother day-to-day coding with improved acceptance shortcuts, reduced IntelliSense conflicts, and better quick-info support.

Microsoft Adds Custom GitHub Copilot Agents to Azure Boards Workflow

Microsoft has announced an update to the Azure Boards integration with GitHub Copilot that introduces support for custom AI agents. The enhancement allows development teams to leverage tailored Copilot agents directly within Azure Boards, streamlining the transition from work items to automated coding tasks.

Here’s what you need to know:

• What are custom agents?

  Custom agents are tailored versions of the GitHub Copilot coding agent, designed to follow your team’s workflows, coding standards, and tool preferences. Think of them as specialized teammates that consistently apply your rules—no need to repeat instructions every time.

• Creating custom agents

  You can define a custom Copilot coding agent by creating a .agent.md profile file in your GitHub repository. This file contains the agent’s instructions, tools, and behavior, making it easy to align Copilot with specific tasks or workflows.

• Using custom agents in Azure DevOps

  Once created at the repository or organization level, your custom agent automatically becomes available in Azure DevOps. When creating a pull request from a work item, you’ll see a new agent selection option alongside the repository list—making it seamless to choose the right agent for the job.

Microsoft Announces Performance Boosts for Visual Studio Editor Extensions

Microsoft is rolling out targeted performance improvements aimed at how editor productivity extensions operate within Visual Studio 2026, part of its broader effort to make the IDE faster and more responsive. The changes stem from a shift in how core editor components are handled, with implications for both users and extension developers alike. Early testing shows these adjustments could significantly reduce startup delays and smooth out the development experience for many workflows.

Here’s what you need to know:

• What’s changed?

  Visual Studio 2026 now supports loading MEF-based editor extensions on background threads using a free-threaded model. This dramatically improves startup performance instead of blocking the UI thread.

• Will this affect your extension?

  Microsoft has introduced a new analyzer to help you identify potential threading issues. It lets you safely test background loading and update your extension to meet MEF rules—so you can benefit from faster startup too.

• Why it matters

  Background loading is key to a faster Visual Studio experience, and it’s being gradually enabled in 2026. The good news? The VS team made it easier than ever to spot issues and fix them—without painful refactoring.

Azure Maps in Power BI Gets Richer Visual Storytelling with Markers

Microsoft has rolled out a new Markers feature for the Azure Maps visual in Power BI, enabling users to replace basic shapes with meaningful icons and dynamic scaling to bring location data to life. The update simplifies map-based storytelling—letting analysts visualize deliveries, assets, or performance metrics without complex GIS tools.

Here’s how it can elevate your map visualizations:

• Markers capability

  Use meaningful icons or custom images, dynamically scale marker sizes, customize colors and transparency, and assign distinct icons by category—all to make your data instantly understandable.

• Real-world use cases

  Markers can be used in logistics and supply chain to visualize delivery routes and shipment volumes using truck icons. In utilities and operations, they help represent asset types, operational statuses, or outage locations. Retail and distribution teams can also use distinct icons and colors to differentiate store categories or performance levels.

• How to get started

  In Power BI Desktop or Web, add the Azure Maps visual to your report and include Latitude, Longitude, and PathID in the Build pane. In the Format pane, go to Markers, select Icon as the marker type, then choose an icon, adjust its size, and use fx on Rotation to bind an angle column for dynamic icon rotation.
