Final .NET 9 Preview Ships with Go-Live License

Visual Studio developers can now download the SDK for .NET 9 Release Candidate 2 with a go-live license, meaning devs get Microsoft support for production applications even before the framework reaches general availability next month.

At this point, of course, all the bits are pretty much set in place and the team has basically been polishing things up.

With "no new features added," release notes for various properties show a couple items of interest as highlighted by Microsoft, including:

  • .NET MAUI: Xcode 16 and latest platform SDK versions -- Compatibility with Xcode 16, which includes SDK support for iOS 18, iPadOS 18, tvOS 18, and macOS Sequoia 15, is now available and is required when building with this release.
  • ASP.NET Core: Updated to latest Bootstrap, jQuery, and jQuery Validation versions -- The ASP.NET Core project templates and libraries have been updated to use the latest versions of Bootstrap, jQuery, and jQuery Validation, specifically:
    • Bootstrap 5.3.3
    • jQuery 3.7.1
    • jQuery Validation 1.21.0

Other minor tweaks and fixes are listed in release notes for SDK and Runtime and Libraries.

Devs can see a roundup of all the new features coming next month at Microsoft's "What's new in .NET 9" documentation, updated yesterday.
