ReSharper for Cursor
In a Nutshell
ReSharper integrates into Cursor as a deterministic, solution-aware code analysis layer that catches AI-generated issues like outdated syntax, N+1 queries, dropped cancellation tokens, and dead code—without consuming tokens. It provides instant navigation, inlay hints, refactorings, postfix templates, and testing/debugging support to review and maintain AI-written code. The core takeaway is using ReSharper's "trust but verify" approach: let Cursor's AI generate code quickly, then rely on ReSharper for reliable, zero-token verification and cleanup.

Cursor is a fantastic environment for AI's development, but the .NET tooling side has been a bit thin. And that's where ReSharper comes in. In this video, we will take a look at what it catches, what it speeds up and the role it plays when an agent is writing half your code. Cursor's AI is excellent, the composer, the context awareness, the multi-file edits, but unless you want to ship it YOLO style, your code really needs a second pair of eyes that never miss a beat. ReSharper helps you with exactly that.
It's instant, it's deterministic, it's fully solution aware and doesn't even require tokens. Call it the trust but verify approach. AI gets your places fast and ReSharper makes sure you land in one piece.
The installation is straightforward. Open the extensions view, search for ReSharper and you will find it on the open VSX registry. Click install, confirm your license, choose your region and you're ready to go. If there is a single solution at your workspace root, ReSharper picks it up automatically.
Otherwise, like with nested folders or multiple solutions, there is an open solution action in the command palette.
For that bird's eye view, you've got the solution explorer. It shows your full solution structure beyond just files and folders, including projects, references and source generators with their generated files. You can also manage your NuGet dependencies, like adding new packages, updating to the latest versions or removing the ones you're not using anymore.
Code analysis has always been at the heart of ReSharper and here's what that looks like in an AI assisted workflow. The agent is writing code and ReSharper is already flagging issues before it's even done.
AI models sometimes miss newer C# syntax or better .NET APIs. Knowledge cutoffs are real. You could prompt your way through it but that takes time and tokens. ReSharper catches these early on, hit Alt+Enter and you can apply quick fixes across your entire solution.
LLMs also tend to miss some subtle framework-specific issues. Think of Entity Framework queries causing N+1 problems or cancellation tokens that are quietly getting dropped from async chains. These often require deep understanding of your code and ReSharper knows the patterns.
If you ever had long prompting sessions, you will know that things can get left behind. Unused methods, variables that no longer serve a purpose, branches that can't be reached. That's dead code noise and the less of it, the better for you and your agents.
For my personal projects, I'm actually planning to tighten up the safety net. Let the AI generate fast but make ReSharper pickier about what gets through. You can erase severities to catch more upfront and suppress specific cases when needed.
Now AI-assisted coding, or vibe coding if you will, is all fun and games until you need to understand or explain what your code actually does. Navigation keeps you oriented as your codebase evolves. You can jump to any symbol, whether by CamelHumps, fuzzy match or whatever gets you there fast.
To trace code dependencies, you can use the context menu with all the essentials. Find references, go to implementation, value tracking, call and type hierarchies. Depending on the action, you will navigate directly or see results in a tool window. If you just want a glance without leaving your code, there are peak navigation equivalents. For example, you can quickly inspect the implementation of a type, which by the way also works with third-party code using decompilation and source link.
Eventually, you want to comprehend your code, but there can be a lot that it doesn't tell you right away. What does this LINQ Select produce? What conversions are happening? What am I passing 'true' for? Inlay hints service that information, which makes reviewing AI-generated code much easier.
As for producing code, sometimes we just want to explore APIs or perform small changes and that should still feel effortless. Code completion with auto-imports, refactorings to rename symbols, extract methods or introduce variables. All the things that are faster to just do than to explain to your agent.
ReSharper also comes with templates to help with boilerplate code, file templates, live templates, and my favorite, postfix templates. Start with a collection type '.forEach' and ReSharper wraps it in a loop with a smart variable naming and the caret placed right in the body.
For testing, ReSharper supports NUnit, XUnit and MSTest. Run a single or multiple tests from the gutter, see the output in a tool window and when something fails the exception shows inline right in your code. The test explorer keeps everything organized so you always know where you stand.
In the latest version, ReSharper also supports debugging. Hit F5 and find a list of runnable projects and launch profiles. Set breakpoints, navigate call stacks or inspect locals and watches. Editing launch.json files also becomes easier with code completion.
So that's ReSharper in Cursor. Deep code analysis, fast navigation, refactorings, unit testing and debugging. All instant, all deterministic, no tokens required. ReSharper for Cursor is available now. Your existing ReSharper, dotUltimate, or All Products Pack license has you covered. For non-commercial use, it's free. Ready to try it? Install it from the Open VSX registry. Links are in the description. Let us know which feature clicks for you and happy coding!
