アプリケーションの動作をリアルタイムで監視

ReSharper is a productivity and code quality plugin for Visual Studio, developed by JetBrains. It helps .NET developers write cleaner, more efficient code. By analyzing code on-the-fly, ReSharper identifies potential errors and suggests fixes. It also automates code refactoring, allowing developers to safely restructure their codebase. These features improve developer productivity and maintainability of the code, making ReSharper a valuable tool for both individual developers and development teams.

The ReSharper 2026.1 update introduces a new monitoring window that brings together runtime metrics, profiling insights, and dynamic program analysis into a single view. It allows developers to observe application performance in real time, whether running normally or under debugging, making it easier to understand system behaviour as it happens.

ReSharper is licensed per user, and is available as a commercial annual subscription license. We can supply new subscriptions, subscription renewals, lapsed renewals, and additional user licenses. See our ReSharper licensing page for full details.
