Visual Studio 2022 v17.12 Preview 1 is now available, and Visual Studio 2022 version 17.11 is now generally available. The 17.12 preview comes with the ability to work with .NET 9 projects and with new AI productivity features.

.NET 9 is also in preview, and the latest update has enhancements for Blazor and MAUI. It also includes C# 13, improvements to ASP.NET Core, and .NET Aspire for apps aimed at Kubernetes.

Microsoft describes .NET Aspire as an "opinionated, cloud-ready stack for building observable, production ready, distributed applications." It is delivered through a collection of NuGet packages that handle specific cloud-native aspects of development, and is available in preview for .NET 9.

The Visual Studio IDE has been updated to make working with .NET and ASP.NET "more delightful than ever", according to Microsoft. In more practical terms, this seems to consist of better code search and an improved debugging experience for Blazor WebAssembly apps targeting .NET 9 or later, so that data types shown in the debugger now match the expected .NET data types; and the displayed call stack is cleaned up to only shows the .NET call stack.

AI productivity improvements come from improvements to GitHub Copilot that are unique to Visual Studio. There's more context from the IDE so developers should see more accurate suggestions. This is combined with more fine-tuned code generation.

The new version has the option to dock the new code search window, and there's a visual preview addition with a "go to line" option.

GitHub support has been enhanced with the ability to create private repositories directly from Visual Studio to avoid the situation with earlier versions where developers accidentally created public repositories making confidential information accessible.

C++ developers should also see improvements, including to the version released as part of v17.11, with a better open source standard library implementation, and advances in the formatted output implementation to include range formatter for ranges, pairs and tuples. There are also improved error messages for some errors, particularly for range tuples.

Visual Studio 2022 Preview 1 of 17.12 and Visual Studio 2022 17.11 are available now.
