Visual Studio April update adds autonomous cloud agents and a new debugger agent

The April update introduces remote sessions for PR generation and a debugger agent that validates fixes against runtime behavior.

Microsoft has just released the April update for Visual Studio 2026 with a focus on cloud agent integration. Cloud agents run on remote infrastructure, enabling scalable, isolated execution, and now you can start new sessions directly from Visual Studio. Also, custom agents now support user-level definitions that travel across projects, C++ code editing tools for agent mode are generally available, and a new Debugger Agent that validates fixes against real runtime behavior is now available.

With the new cloud agent integration, you can now start sessions from within Visual Studio. Just select Cloud from the agent picker in the Chat window and describe what you need help with and the cloud agent will handle it. The cloud agent is powered by the Copilot coding agent, so you need to ensure you are in a GitHub repository and that Copilot has permission to create issues in that repository. Microsoft says that this feature frees you up to focus on parts of your project that need your full attention.

This update also allows you to create custom agents that travel with you across projects, building on initial support that arrived last month that let you create custom agents for individual repositories. Everything that you could do with repository agents still works such as workspace awareness, code understanding, tools, model selection, and MCP connections to external knowledge sources.

This update also makes C++ Code Editing Tools for GitHub Copilot agent mode generally available by default. These give Copilot language-aware navigation in C++ codebases, helping to map out class inheritance hierarchies and follow function call chains when refactoring or modifying code. Microsoft says this makes a big difference when working with large C++ codebases.

This update also brings the new Debugger Agent which helps to validate bugs against real runtime behavior, customizable Copilot keyboard shortcuts for accepting Copilot inline suggestions, and now IntelliSense completions take precedence over Copilot ones, following users feedback.
