Visual Studio’s September Update Has Arrived: Here’s What’s New

Visible Studio might be top-of-the-line IDEs on the market, particularly with regards to Home windows apps. Now, it simply bought rather a lot higher with a brand new set of options—together with quite a lot of AI stuff that ought to make your growth expertise much more nice.

Visual Studio has rolled out its new September replace, and it is packing quite a lot of new stuff. We have now a brand new Profiler Agent, which works as an AI assistant that analyzes utility efficiency to determine and assist resolve points. Integrating straight with GitHub Copilot, the agent examines CPU utilization, reminiscence habits, and .NET object allocations to pinpoint efficiency bottlenecks. Based on the announcement, it will probably counsel particular code optimizations, create or refine efficiency benchmarks utilizing the BenchmarkDotNet framework, and information builders by a validation loop to substantiate enhancements.

Alongside efficiency tuning, the replace introduces the GitHub Copilot App Modernization Agent. This software is particularly geared toward builders managing legacy .NET purposes. The agent assists within the strategy of upgrading tasks to more moderen variations of the .NET framework and facilitates migration to Microsoft’s Azure cloud platform. Builders can work together with the agent by the Copilot Chat window or a brand new context menu choice within the Answer Explorer.

The replace additionally contains native help for producing and rendering Mermaid diagrams straight inside the Visible Studio Markdown editor, a functionality that beforehand required exterior extensions. Builders can now use pure language prompts to ask Copilot to generate varied diagrams—together with architectural, sequence, flowchart, and sophistication diagrams—to visualise advanced code constructions, API name flows, or system parts. Copilot analyzes the codebase for context and produces the corresponding Mermaid syntax, which may then be previewed as a visible diagram.

For collaborative growth, the native code evaluation course of has been considerably upgraded. The characteristic now makes use of the identical superior reasoning fashions that energy code critiques on the primary GitHub platform, bringing a better high quality of study straight into the IDE. The software critiques native adjustments earlier than a commit and offers inline feedback and ideas inside the “Git Adjustments” window. To provide groups extra management, the system now helps customized directions for Copilot by a devoted markdown file within the repository root.

Copilot’s “Agent Mode” has obtained updates to enhance efficiency and reliability, together with clearer progress indicators and improved immediate caching. A notable replace is new immediate formatting optimized for future “GPT-5 fashions” and an experimental planning software that breaks down advanced requests into smaller steps.

This replace is now obtainable for builders, so obtain it now to make the most of all of this.
