Part of ReSharper Ultimate
Code analysis with ReSharper

ReSharper extends Visual Studio with over 1700 code inspections for C#, VB.NET, ASP.NET, JavaScript, TypeScript and other technologies. For most inspections, ReSharper provides quick-fixes (light bulbs) to improve code in one way or another.

Navigation and search with ReSharper

ReSharper helps instantly land at any code in a solution, no matter how large it is. It can also navigate you from any symbol to related code such as implementations of a given interface, extension methods of a class, or usages of a field.

Refactoring with ReSharper

40+ refactorings and 200+ context actions help safely organize code and move it around the solution, distribute responsibility, decouple, decrease complexity, or simply use alternative language syntax.

Code formatting and cleanup with ReSharper

Configure and apply code style whichever way is best for you or your team. Code style and formatting settings for C#, VB.NET, ASP.NET, JavaScript, TypeScript and other languages can be applied in any scope, from a selection to a solution.

Code generation with ReSharper

ReSharper can create a lot of code for you: from new files and classes to conditional blocks and GUIDs; from methods and properties required by an interface being implemented to equality checks and formatting members.

How ReSharper Helps Visual Studio Users

Analyze code quality

On-the-fly code quality analysis is available in C#, VB.NET, XAML, ASP.NET, ASP.NET MVC, JavaScript, TypeScript, CSS, HTML, and XML. You'll know right away if your code needs to be improved.

Eliminate errors and code smells

Not only does ReSharper warn you when there's a problem in your code but it provides hundreds of quick-fixes to solve them automatically, in the best possible way.

Safely change the code base

Automated solution-wide code refactorings help safely change your code base. Whether you need to revitalize legacy code or put your project structure in order, you can lean on ReSharper.

Instantly traverse the entire solution

You can instantly navigate and search in the whole solution. Jump to any file, type, or type member, or navigate from a specific symbol to its usages, base and derived symbols, or implementations.

Enjoy code editing helpers

Multiple code editing helpers include extended IntelliSense, hundreds of instant code transformations, auto-importing namespaces, rearranging code and displaying documentation.

Comply to coding standards

Code style and formatting functionality with fine-grained, language-specific settings will help you get rid of unused code and create a common coding standard for your team.

In other ways

As if the above isn't enough, there are other areas where ReSharper helps Visual Studio users, such as generation of common code, extensible code and file templates, internationalization assistance, diagrams to visualize project and type dependencies, as well as a unit test runner.

Type Dependency Graph

ReSharper 9 expands its set of Architecture Tools with a Type Dependency Graph that shows what code depends on a particular type, and what the type itself depends on.

More Bulk Fixes

ReSharper 9 allows removing redundant qualifiers, fixing naming problems and removing regions in the scope of a file, project or the whole solution.

What ReSharper Users Say

I love ReSharper! Its tightly integrated unit testing makes it a joy to do test-driven development, its automated refactorings are nothing short of superb and its code suggestions routinely help me write better C#/VB.NET code.

The ultimate Agile tool is ReSharper. It is the one thing for .NET developers that removes fear of change. Refactoring is just so darn easy that change isn't scary.

ReSharper is an awesome tool. If you're using it you probably agree and if you aren't you should be. The productivity gains are incredible. The moment you see another developer step effortlessly through the code you'll agree.
