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 almost every case, you can select the best quick-fix from a variety of options.

Safely change the code base

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

Instantly traverse the entire solution

You can instantly navigate and search through 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 including extended IntelliSense, hundreds of instant code transformations, auto-importing namespaces, rearranging code, and displaying documentation.

Comply with coding standards

Code style and formatting functionality with fine-tuned, 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 2200 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 the code.

Find and remove unused code? Migrate your code to C# 7? Convert loops to LINQ at will? Find and prevent possible exceptions? Use a common naming standard? All that and a lot more code improvements are made possible with ReSharper's code analysis.

Refactorings

60+ refactorings and 450+ 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 get to any code in a solution, no matter how large the solution is. It can also navigate you from any symbol to its 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.

What's New

Why upgrade to ReSharper 2018.3

Inline parameter name hints for C# and VB.NET

Inline parameter name hints for C# and VB.NET

We’ve added parameter name hints right to the code editor to make C# and VB.NET code more readable. When a literal is used in a method call ReSharper annotates it with the name of the parameter, making it much easier to understand what value it represents.

Visual Studio 2019 support

Visual Studio 2019 Preview 1 support

Starting with version 2018.3, ReSharper has early support for Visual Studio 2019 and can be integrated into Visual Studio 2019 Preview 1 build. Full support will be available in ReSharper 2019.1 after the official release of Visual Studio 2019.

Auto-detection of formatter settings and the naming style

Auto-detection of formatter settings and the naming style

Have you spent a lot of time in ReSharper options trying to configure formatter settings to follow your style? No more struggling! ReSharper detects code formatting style from your code and adjusts the formatter settings accordingly (ReSharper | Edit | Detect formatting settings).

ReSharper now detects the naming style used in the code to follow that naming convention and doesn't highlight most of the entities declarations with ‘Inconsistent naming’ warnings like it used to.

All I can say is I love it. If you don't use ReSharper, drop what you are doing and go out and buy it!

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.
