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.

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 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

Code Issues

We improved analysis of async code patterns, adding new code issues to report situations where code may be missing an intended 'await':

inside try and using statements, which could cause problems with exception handling and premature object disposal
inside synchronous code, effectively producing fire-and-forget tasks

Context Providers

We added two new context providers [DebugRunMode] and [DebugBreakMode]. You can use them to setup context for keyboard shortcuts, templates, and any other feature that supports context.

Improved Visual Studio 17.14 support

We patched a number of CodeRush features to work correctly with the recent Visual Studio 17.14 release.
