CodeRush Feature Overview

AI-Powered Development (AiGen)

CodeRush's AiGen feature brings real-time, context-aware AI assistance directly into the editor. AiGen analyzes your code, project structure, and editor state to quickly deliver precise changes exactly where they’re needed. AiGen helps you refactor, generate, fix, and evolve code using natural requests spoken or typed directly from Visual Studio.

Apply surgical code updates without waiting for AI to regenerate entire methods/types
Generate tests from live debug-time values
Analyze and correct active compiler errors
Safely integrate changes even while you continue editing
Run multiple AI requests in parallel for independent tasks targeting the same type/file/project/solution
Perform cross-file architectural updates across the entire solution
Use natural voice prompts or text commands

AiGen is optimized for real development workflows - from small surgical edits to large multi-file changes - while keeping AI output minimal, fast, and cost-efficient. AiGen requires an API key from OpenAI or Azure. Learn more about AI-Powered Development

Code Generation & Typing

Create new code more efficiently with CodeRush's intelligent code generation. Declare members in a single keypress. Surround code with try/catch or using blocks (again, in a single keypress).

Write Boilerplate Code Faster and with Fewer Keystrokes
Add Using Directives and Common Member Implementations Instantly
Create Code Elements Intelligently Based on Usage
Surround Selected Code with Popular Language Constructs
Intelligently Create New Code Based on a Sample Selection

Code Refactoring & Transformation

With over 100 refactorings and intelligent code providers, CodeRush delivers the power you need to easily change code, improving readability and the internal structure without changing external behavior.

Safely make changes to the API (add/remove parameters, add interface members, move members up the hierarchy) or update legacy code to support new language features. Focus more on code quality and functionality, and let CodeRush handle the routine changes to the code base.

Move through your code at warp speed. CodeRush includes innovative, powerful and exclusive tools that help you be exactly where you want to be in an instant, regardless of solution size.

Code Style & Formatting

With a rich set of code style settings, you get to focus on code quality and functionality while CodeRush focuses on matching the style needed in the moment. And code style settings can be separately configured (if needed) for yourself, individual solutions, and your entire team.

You can format code, remove unused code, and sort and group members in a single action. You can do this for the active file or instantly clean up entire folders or projects. CodeRush gives you complete control over the entire process.

And if you like, CodeRush will clean up code automatically (to your specifications) when saving documents.

Whether it's Style Cop guidelines or any other style you prefer, CodeRush can organize your code and make it easier to read.

Code Visualization & Readability

CodeRush can add code visualization features to Visual Studio, improving code quality and readability, and help you more easily create and debug code.

Features include:

Highlight and Correct Misspelled Words in Code, Comments, and Strings
Preview Expression Values In-place while Debugging
Perform Common Tasks with Type Members with a Single Click
Highlight Code Blocks and Region Boundaries
Make Sure All Your Code Fits Onscreen with a Right Margin Indicator Line

Code Coverage & Testing

When it comes to Test Driven Development, CodeRush is the tool of choice. CodeRush's Test Runner is top of its class. It's the fastest test runner available for .NET. Run and debug a single test, or all tests in the solution. You can even focus on a group of related tests using the Sessions functionality. In-source icons let you run, debug, and see test run status directly from code. And it simply works across test frameworks without any configuration required.

NUnit, MSTest (VS Testing), xUnit, and MSpec tests all are working right out of the box. .NetCore (including .Net 5 and .Net 6), .Net Framework, and multi-target projects are also supported.

CodeRush Templates make it easier to create new tests with a simple keystroke, while Code Coverage helps your entire team find problem areas in the code. You can even reveal line-by-line coverage details if you like.

What's New in the latest version

Test Runner

We added support for MSTest v4.

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.
We 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 (e.g., "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.
