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.

The following features may not operate as intended with OOP mode enabled:

  • AI-powered features

  • DPA, dotMemory, dotTrace, dotCover integrations
  • Template editor
  • Structural Search and Replace
  • Regular expression validation
