Jetbrains ReSharper

What is included in JetBrains ReSharper?

Code Analysis – Real-time inspections and quick-fixes as you type.
Safe Refactorings – Solution-wide rename, extract, move and inline.
Code Navigation – Jump to symbols, usages and decompiled sources.
Out-of-Process Mode – Runs analysis in a separate worker process.
Core Capacity – C#, VB.NET, XAML, Razor, JavaScript and TypeScript.
Important – Runs only inside Visual Studio on Windows.

What are the main benefits of JetBrains ReSharper?

JetBrains ReSharper is a productivity extension for Microsoft Visual Studio that adds deep static analysis, automated refactorings and fast navigation for C# and other .NET languages. It helps developers fix code issues while typing and reshape large solutions without breaking the build.

Faster Refactoring – Reshape large solutions without breaking references.
Early Bug Detection – Catch errors and code smells while typing.
Consistent Code Style – Enforce one formatting standard across the team.
Quick Navigation – Reach any symbol or usage in seconds.
Responsive Editor – Out-of-Process mode keeps Visual Studio fluid.
Latest .NET Ready – Same-day C# 14 and .NET 10 support.

What does JetBrains ReSharper do?

ReSharper analyzes your .NET code in real time inside Visual Studio and offers fixes, refactorings, navigation and code generation. It flags errors, code smells and style violations as you type and applies most corrections through a single Alt+Enter menu. It covers C#, VB.NET, ASP.NET, Razor, Blazor, XAML, JavaScript and TypeScript, but not C++, which is handled by the separate ReSharper C++ product. In daily work this shortens code review, because unused code, null-reference risks and inconsistent formatting are caught before the code ever reaches a teammate.

Does ReSharper work in Visual Studio Code, or only in Visual Studio?

The classic ReSharper described here runs only inside Microsoft Visual Studio on Windows. On 5 March 2026, JetBrains released a separate product, ReSharper for VS Code, that brings C# analysis and refactoring to Visual Studio Code, Cursor and Google Antigravity. The two share a subscription but are different installations, so buying ReSharper for Visual Studio does not turn VS Code into a full ReSharper editor by itself. If you need a standalone, cross-platform .NET IDE for macOS or Linux, JetBrains Rider is the correct product rather than this Visual Studio extension.

Is JetBrains ReSharper free, and does it need a commercial license?

ReSharper for Visual Studio is not free and has no non-commercial free tier. JetBrains offers free non-commercial licenses only for ReSharper for VS Code and for Rider, not for ReSharper inside Visual Studio. New users can run a 30-day trial of the full extension before deciding. Any paid development work in Visual Studio requires a commercial license, so teams shipping software for money cannot substitute the free VS Code tier for the Visual Studio extension.

What is the difference between ReSharper, ReSharper C++ and dotUltimate?

ReSharper covers .NET languages, ReSharper C++ covers C++, and dotUltimate bundles both together with the profilers, code coverage and the Rider IDE. The table below shows what each one includes so you can match the purchase to your actual stack.

Choose ReSharper for C# and VB.NET work inside Visual Studio. Choose dotUltimate if you also need dotTrace and dotMemory profiling, dotCover coverage, or the standalone Rider IDE for cross-platform projects.

Does ReSharper slow down Visual Studio?

ReSharper has historically added load to Visual Studio because it ran inside the same UI process, and recent versions address this directly with Out-of-Process (OOP) mode. OOP mode, available as a preview from 2025.2 and refined since, moves most analysis into a separate 64-bit worker process, and in 2026.1 that process runs on the .NET 10 runtime. The practical effect is that typing and scrolling stay responsive on large solutions, which was the most common complaint from heavy users. On very large codebases more RAM still helps, and enabling OOP mode is the first setting to check if responsiveness matters to you.

Which languages and frameworks does ReSharper support?

ReSharper supports C#, VB.NET, ASP.NET, Razor, Blazor, XAML, JavaScript, TypeScript, HTML, CSS and build scripts. It does not include C++ support, which is a separate product, ReSharper C++, that also adds Unreal Engine tooling. It provides same-day support for new language versions, including C# 14 and .NET 10, so its inspections and refactorings understand new syntax on release day. This matters if your team adopts new .NET versions early, because you avoid the gap where a tool flags valid modern code as an error until a later update.

Frequently asked questions about JetBrains ReSharper

Does ReSharper include AI features?

ReSharper integrates JetBrains AI features, but they are a separate, optional layer rather than part of the core analysis engine. The non-commercial tier includes only a short AI services trial, and full AI use requires a JetBrains AI subscription. All inspections, refactorings and navigation work without any AI subscription at all.

Is ReSharper compatible with Visual Studio 2026?

Yes. ReSharper 2025.3 and later are compatible with Visual Studio 2026 and ship support aligned with the latest compiler changes. Keeping the extension on its current release line is the safest way to stay aligned with new Visual Studio updates.

Can ReSharper settings be shared across a team?

Yes. ReSharper stores settings in layers, including a solution-team-shared layer that can be committed to version control so everyone uses the same inspections and formatting. It also reads EditorConfig, which lets ReSharper rules and your existing project style stay consistent across the whole team.
