Visual Studio 2026 Insiders can now easily use Copilot from the right-click menu. With text selected, you can explain and comment on the code you selected. With no text selected, you can perform actions on the code near the cursor or the entire file.



Copilot's response capabilities have also been enhanced, allowing you to specify a line number to perform an operation.



You can also enter a URL to view information on a web page.



Additionally, you can use various AI models by entering your API keys from OpenAI, Google, and Anthropic.



It also supports Mermaid-style flowchart drawing, making it easy to run a series of flows where AI creates and displays flowcharts. Of course, you can also create your own diagrams.



The UI has also been revamped to coincide with the update to Microsoft's design language,

Fluent UI , and 11 new color themes have been added.



There is also an option to customize just the appearance of the editor portion.



In addition, the icon image has been replaced with a new one.
