THE READ
What the cluster adds up to.
The release of Rider and ReSharper 2026.2.2 brings significant updates, with a focus on improving the workflow for developers using AI agents. The AI Agent Setup widget centralizes access to coding agent features, allowing users to easily navigate and configure tools relevant to their projects. This could reduce the time spent on setup and increase efficiency in development environments where AI integration is utilized.
The addition of TUnit support for test coverage represents a notable enhancement for unit testing within the Rider and ReSharper environments. Developers will now be able to measure test coverage more effectively, which is essential for ensuring that code is robust and well-tested. To take advantage of this feature, developers must install the JetBrains.dotCover.Framework package and meet the specified version requirements for the Microsoft.Testing.Platform.
Furthermore, the update addresses critical issues that could hinder productivity, such as freezing on macOS and dependency problems with Unity. By resolving these issues, the new version improves the overall user experience and stability of the tools, which is crucial for developers relying on these platforms for their projects. This kind of maintenance not only keeps the software functional but also fosters a more reliable development environment.
