AiGen Performance & Intelligence Enhancements

• Performance & Intelligence Enhancements
  • AiGen now more intelligently gathers and optimally packs context before sending it to the Reasoning AI.
  • AiGen now supports smaller code deltas, enabling fast, surgical-precision AI code changes (targeting member signatures, bodies, attributes, XML comments, and individual code blocks within large methods).
• New AiGen Integrations
  • You can now share your clipboard with AI or ask AI to put content on the Windows clipboard throughout Visual Studio.
  • Added added Azure Endpoint support and context-specific AI endpoint selection.
  • Added DevExpress MCP Server and Microsoft MCP Server integration for authoritative documentation.

Debugging Enhancements

• AiGen support for analyzing active errors, call stacks, and runtime values (for example: "Create a test for this method using these exact same parameter values").

User Experience Improvements

• Added voice support, including recognition and feedback for 100+ spoken languages.
• AiGen can now remember your coding preferences (for example, "I want you to remember that I prefer field variables to start with a lowercase letter - no underscore." ). Remembered state is stored on the Triggered Prompts options page.
