The Swift for Visual Studio Code extension adds first-class language support for projects built with Swift Package Manager, enabling seamless cross-platform development on macOS, Linux, and Windows.

Contracts are a means of setting preconditions and postconditions on function declarations, and adding assertion statements within functions. The feature is intended to help make C++ code safer and more reliable.

After that date, Microsoft will no longer provide security patches, bug fixes, or technical support for ASP.NET Core 2.3. Users are advised to upgrade to modern ASP.NET on .NET 10.

New overloads on TarFile.CreateFromDirectory accept a TarEntryFormat parameter, giving direct control over the archive format. Previously, CreateFromDirectory produced Pax archives. The new overloads support all four tar formats—Pax, Ustar, GNU, and V7—for compatibility with specific tools and environments.

This is achieved via Model Context Protocol (MCP), an open protocol that lets AI agents work with external tools and structured resources. Xcode acts as an MCP endpoint that exposes a bunch of machine-invocable interfaces and gives AI tools like Codex or Claude Agent access to a wide range of IDE primitives like file graph, docs search, project settings, and so on.

Dependabot sounded the alarm on a large scale. Thousands of repositories automatically received pull requests and warnings, including a high vulnerability score and signals about possible compatibility issues. According to Valsorda, this shows that the tool mainly checks whether a dependency is present, without analyzing whether the vulnerable code is actually accessible within a project.

If there's one universal experience with AI-powered code development tools, it's how they feel like magic until they don't. One moment, you're watching an AI agent slurp up your codebase and deliver a remarkably sharp analysis of its architecture and design choices. And the next, it's spamming the console with "CoreCoreCoreCore" until the scroll-back buffer fills up and you've run out of tokens.

The reason for this is Snap - a Linux application packaging format - creates a local Trash folder for each VS Code version, one that's separate from the system-managed Trash, according to a VS Code bug report dating back to November 11, 2024. Not only that, but Snap keeps older versions of VS Code after updates, potentially multiplying the number of local Trash folders and the trashed-but-not-deleted files therein. Emptying the system Trash folder doesn't affect the local instances.

The headline runtime feature in this preview is Runtime Async, described as a major change to how asynchronous methods work in .NET. According to the release notes, since C# 5 introduced async/await, the compiler has been solely responsible for rewriting async methods into state machine structs that track progress across suspension points. With Runtime Async, the runtime itself now understands async methods as a first-class concept and takes over responsibility for suspending and resuming methods.
