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.

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 in ReSharper

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 2020.1

Dataflow analysis of integer values in C#

Dataflow analysis of integer values in C#

This version of ReSharper introduces a new type of C# code analysis to track the usage of integer values in your application. This new type of analysis tracks how the values of all int local variables vary, and it verifies the correctness of all common operations on such variables to detect useless or possibly unnecessary pieces of code.

Even Better C# 8 support

Even Better C# 8 support

We continue to add more and more support for C# 8 language features. We’ve refactored a lot under the hood in C# language support to prepare code analysis and other features, such as refactorings and ReSharper Build, to support nullable reference types (NRT). In ReSharper 2020.1, code analysis reports compilation warnings related to nullable reference types and provides quick-fixes for most of them.

Improved XAML support

Improved XAML support

In v2020.1, we’ve made a lot of improvements and fixes to XAML support that cover WPF, Xamarin.Forms, UWP, and Avalonia XAMLs. 

We are happy to provide much better support for data context inference and symbol resolution in bindings.

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.
