Improved experience running multiple projects

The new Run Multiple Projects feature in Rider 2023.3 allows you to set up custom multi-launch configurations to ensure all of your solution’s dependencies are handled flawlessly.

Type dependency diagrams

Type dependency diagrams in Rider 2023.3 provide a visual representation of how different elements in the codebase interact with each other, making it easier to grasp your project’s design and adding clarity to debugging.

Predictive debugging

Predictive debugging is a new advanced debugging mode for Rider that predicts potential issues in your code and alerts you to them without the need to execute the code.

Learn all about this feature from the dedicated blog post.

In addition to gaining a predictive debugging mode, Rider 2023.3 also now boasts a new Modules view that lets you inspect the dynamic link libraries (DLLs) and executables that your app uses. 

Creating and navigating through unit tests

You can now easily navigate and create tests for your production code using Rider. With this release, we’re also introducing the ability to generate the tests using AI Assistant.

Learn more about creating and navigating through unit tests from Rider’s documentation.  

Performance enhancements

Rider 2023.3 puts you in control of the amount of resources to be allocated to solution-wide code analysis. You can now choose between Low, Moderate, and High modes of resource utilization.

  • The Run button in the main toolbar has been replaced with a Resume button during debugging.
  • Rider can now help you quickly create solution filter files to tailor your IDE’s Project view to the specific context you’re working in.
  • There’s now an option to hide the main toolbar in the default viewing mode to visually declutter your workspace.
  • The Speed Search functionality, allowing you to quickly navigate within tool windows and dialogs, is now available via a shortcut.
  • There’s a new product icon for Rider on macOS that matches the style guidelines of the operating system.

Game development


Rider 2023.3 comes with UI Toolkit support. The IDE will now show you where UI elements are used in UXML files, help you navigate from elements in UXML files to C# code, and provide code completion for UI elements in C# queries.

The latest update also contains shader variant support. A new optional preview feature allows you to select the keywords that are active while editing a shader file. 

The debugging experience for Unity projects in Rider has been improved in several ways. We’ve also added plenty more small fixes and features, such as completion of semantics in HLSL code and fixes for both online help URLs for packages and incorrect warnings for certain DOTS scenarios. 

Unreal Engine

A significant new feature allows Rider to only recognize symbols from explicitly included files and ignore anything imported by pre-compiled header (PCH) files. This allows local builds to use PCH files for improved compilation speeds while ensuring correctness for CI build servers.

More details on game development updates can be found here.

Web development

The latest major update to Rider offers some handy tweaks for working with TypeScript, improved Angular support, and a number of other valuable enhancements. 

Check out the What’s New in WebStorm 2023.3 page to learn about these and other updates to web development available in Rider.

Remote development

A lot of effort has been put into improving the typing experience when using remote development in Rider 2023.3. The enhancements have made all aspects of typing in the editor more convenient, including code completion, context actions, and popups.
