Rider Early Access Program

Rider 2025.1 EAP 8 comes with the following updates:

Remote development in Rider is moving to JetBrains Toolbox

Starting with the 2025.1 release, remote development in Rider can now be managed through the JetBrains Toolbox App. While Gateway remains available for remote access to Linux machines, the transition to Toolbox has begun, with the goal of making it the primary access point for remote development in future releases.

The latest Early Preview build for Toolbox introduces full remote development support, allowing you to connect to Windows, macOS, and Linux hosts, set up SSH access with OpenSSH, and keep all your projects in one place.

For more details and a step-by-step guide, check out this blog post from the Toolbox team.

Support for Azure Function projects

Rider 2025.1 now supports running and debugging Azure Function projects via the .NET Aspire and the Azure Toolkit for Rider plugins. Please share any feedback you may have on the functionality in the comments to this ticket.

Support for AWS Lambda Function projects in .NET Aspire

The .NET Aspire plugin now also supports running and debugging AWS Lambda Function projects in Rider. For more information, please see this GitHub issue.

Rider 2025.1 EAP 7 is out

This release contains smaller bug-fixes and improvements to the performance and stability of the IDE.

For full information about the changes included in this build, please see our issue tracker.

Rider 2025.1 EAP 6 comes with the following updates:

New Detach button for C++ debugging

Rider now offers a Detach button when debugging C++ applications. You can now detach from a running C++ process without terminating it, allowing the application to continue executing independently. 

The Detach button can be found in the Run/Debug menu during the debugging of C++ applications or on the toolbar of the Debugger tool window.

String interpolation support in the Decompiler tool window

Support for C# string interpolation is now available in the decompiler, making the output more readable and aligned with modern C# best practices.

The decompiler will now automatically transform string.Concat and string.Format calls into C# string interpolation where applicable.

For full information about the updates included in this build, please see our issue tracker.

Rider 2025.1 EAP 5 comes with the following updates:

• Roslyn syntax tree visualizer
• Support for dotnet watch as a run/debug configuration
• Input/output redirection for run configurations
• Enhanced C++ debugging on Windows
• Unity Profiler integration

Rider 2025.1 EAP 4 comes with the following updates:

Game development

NoesisGUI framework support: We've added support for the NoesisGUI for Unity and Unreal Engine projects, expanding the range of C++ game UI libraries available for game development in Rider.

We've also resolved an issue where the NoesisGUI preview on Windows would get stuck in an endless loading state. [RIDER-122145]

Godot improvements: Rider now supports .uid files in Godot 4.4. When files are moved within Rider, the corresponding .uid files are moved together to maintain project integrity.

C++ native debugger (LLDB) improvements for Windows

In addition to the performance enhancements we revealed in EAP 2, we've also made improvements to Natvis support, stepping accuracy, and debugging stability for Unreal Engine and other C++ projects on Windows. Here are some highlights:

• We improved type visualization by adding support for Synthetic items in Natvis, enhancing Unreal Engine debugging. [RIDER-116407]
• We added support for the NVO format specifier in Natvis. [RIDER-120524]
• We enabled Natvis intrinsics in expression evaluation, within other Natvis types, and in conditional breakpoints. [RIDER-111190]
• We added support for char8_t from C++20. [RIDER-120687]
• We added a link to apply an expression fix with a single click. [RIDER-114653]
• We implemented support for exclamation syntax (module.dll!expr) in the context operator for expression evaluation and conditional breakpoints. [RIDER-119956]
• We improved stepping accuracy in debugging. Stop-over no longer falls into inline functions incorrectly, and the Step-in and Step-over actions now stop at the correct lines. [RIDER-119314]
• We resolved an issue where debugging sessions could crash the target process due to access violations, particularly in optimized Unreal Engine builds. [RIDER-121706]

.NET debugger fixes

We've fixed an issue where expressions in the Immediate Window were evaluated twice, ensuring correct debugging behavior. [RIDER-83380]

Code navigation

We added support for the Next Highlighted Usage and Previous Highlighted Usage actions to improve code navigation. [RIDER-15896]

Decompiler improvements

• Support has been added for the allows ref struct generic anti-constraint from C#13. [DOTP-8182]
• Support has been added for ref fields and scoped parameter modifiers. [DOTP-8181]
• Support has been added for file-scoped namespaces. [DOTP-8184]

For full information about the updates included in this build, please see our issue tracker.

Rider 2025.1 EAP 3 comes with the following updates:

• Proper support for Blazor WebAssembly publishing.
• The main menu has been merged with the main toolbar on Windows and Linux.
• The option to set up automatic plugin updates.
• Several decompiler enhancements.

Rider 2025.1 EAP 2 build comes with:

Easier environment variable configuration with .env files

Rider 2025.1 EAP 2 simplifies the management of environment variables. Instead of entering variables manually, you can now use .env files directly in your run/debug configurations.

Look for the folder icon (Browse) next to the Environment Variables field to attach your .env files, and Rider will take care of loading them before launch. You can even use multiple files across different projects to maintain consistent configurations.

A Load .env option is also available as a pre-launch task to ensure your environment variables are ready when your application starts.

Faster debugging for C++ projects

Rider 2025.1 brings faster stepping times to debugging large C++ projects, particularly in Unreal Engine development. Thanks to targeted optimizations in our custom LLDB debugger, delays during step-over and step-into operations have been dramatically reduced. This blog post has all the details. 

Improvements for remote development environments

This build also brings improvements to workflows in Docker containers and other remote environments. Check out this blog post to learn more.

For full information about the updates included in this build, please see our issue tracker.

The first early preview build introduces:

• Repository-wide visibility in the Solution Explorer.
• Automatic child processes attachment for the .NET debugger.
• Enhanced .NET exception breakpoint configuration.
• Separate color settings for C++ keywords.
