ReSharper in OOP Mode: Now Available for Public Preview and Testing
We're excited to introduce the first publicly available builds of ReSharper with support for running out-of-process with Microsoft Visual Studio.
Click the button below to download the latest ReSharper 2025.2 EAP build and follow the instructions to enable OOP mode.
How to take ReSharper Out of Process
After downloading the preview build and installing it in Visual Studio, you can easily enable and switch between OOP and In-process modes:
Enabling OOP Mode
Go to ReSharper's Options | Environment | Products & Features and select the Run ReSharper in separate process option. Click the Save and restart button to apply the changes and reinitialize ReSharper without having to restart the IDE. All ReSharper startups after that will be in OOP mode by default.
Toggling between modes
You can toggle between In-Process and Out-of-Process modes from the bottom-right corner of the status bar as needed. Please review the list of known limitations below to be aware of any potential compatibility issues.
Disabling the OOP mode
As of ReSharper 2025.2 EAP 6 release, the Out-of-Process mode is enabled by default. If you would like to disable it, you can switch back to the In-process mode by going to ReSharper's Options | Environment | Products & Features and deselecting the Run ReSharper in separate process option.
We want to make sure ReSharper works smoothly for you in Out-of-Process mode. Your feedback helps us do that. Let us know which tools, components, or features you rely on most so we can focus on compatibility where it matters. If you choose to disable OOP mode, we'd love to hear why. You can share all of your thoughts with us in this ticket.
