Copilot's 'Auto' model picker in VS Code and Visual Studio currently routes to whatever model is most available and policy-compliant--not the one best matched to your prompt--while Microsoft/GitHub say task-aware routing is planned but not yet shipped.
GitHub's new Agents tab centralizes Copilot coding agent sessions in a repository, making it easier to launch tasks, track progress, and review the resulting pull requests in standard tooling such as Visual Studio
Dr. James McCaffrey presents a complete end-to-end demonstration of quadratic regression, implemented from scratch, with SGD training, using C#. Compared to standard linear regression, quadratic regression is better able to handle data with a non-linear structure, and data with interactions between predictor variables.

A review of five non-Copilot AI coding assistants available in the Visual Studio Marketplace that support Visual Studio 2026 and exceed 100,000 installs.
What a difference a year makes in the fast-moving advanced-AI space! GitHub Copilot's vision and image-based features arrived first in VS Code in February 2025 and have since become more integrated there, while Visual Studio is beginning to add similar capabilities through Copilot Chat in a more limited form. Here's a hands-on demo of what you can do now in both.
C# was named TIOBE’s Programming Language of the Year, while the index also pointed to a potential rise for TypeScript. Here’s how the latest rankings compare across TIOBE, RedMonk, and PYPL.
Strong holiday viewership of advanced VSLive! Orlando sessions points to growing demand for immersive, hands-on training as AI-assisted development and modern .NET architectures reshape how developers work.
Developers on Reddit discussing upgrades from .NET 8 to .NET 10 report few breaking changes, minimal effort, and consistent performance and LTS benefits, even across large, multi-project codebases.
Microsoft has moved C++ into Visual Studio's deepest Copilot tier, adding symbol-aware tools in public preview that let Copilot agent mode refactor and edit large C++ codebases across multiple files, similar to the kind of deep integration long associated with C#
Ted Neward’s "Busy .NET Developer's Guide to Orleans" session at Visual Studio Live! Las Vegas (March 18, 2026) walks .NET developers through the Orleans actor model, showing how it simplifies state, concurrency, and scaling and how it can coexist with traditional .NET APIs. Early registrants can save $500 by the Dec. 19 Year-End Savings deadline.
Dr. James McCaffrey presents a complete end-to-end demonstration of linear regression using pseudo-inverse training. Compared to other training techniques, such as stochastic gradient descent, pseudo-inverse training does not require any parameters and so it is especially simple to use.

Since its Nov. 11 debut, Visual Studio 2026 sees improved Copilot Chat response quality by enhancing semantic code search with remote indexes, expanding awareness of external C# symbols, and increasing accuracy when developers reference specific line numbers, alongside new Copilot features like a GitHub Cloud Agent preview, context-menu actions, and intent detection in All-In-One Search.
Microsoft has been busy adding new features to Visual Studio 2026, which reached general availability on Nov. 11, including several new features driven by AI to enhance developer workflow.
Microsoft says its Go-based "native" TypeScript 7 compiler and language service are now stable enough for everyday editor and CLI use, delivering big speed gains and near-complete type-checking parity, while setting TypeScript 6.0 as the final JavaScript-based release and outlining remaining emit and tooling-API gaps.
Once-buzzy OData continues to move forward at Microsoft, with new .NET 10-aligned tooling previews and an ODataX proposal aimed at easing adoption while preserving the protocol's enterprise-strength querying model.
