Why ReSharper?

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 problems automatically. In most cases, you can select the best quick-fix from a variety of options.

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.

Features

ReSharper makes Visual Studio a much better IDE

Code analysis

ReSharper extends Visual Studio with over 1700 on-the-fly 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.

Find and get rid of unused code? Migrate your code to C# 6? Convert loops to LINQ at will? Find and prevent possible exceptions? Use a common naming standard? All that and a lot more code improvements is made possible with ReSharper's code analysis.

Refactorings

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.

Navigation and Search

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.

Code formatting and cleanup

Configure and apply code style based on your personal preferences or your team standard. 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

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.
