Out-of-Process mode
This long-anticipated architectural change decouples the ReSharper process from the Visual Studio one and lays the foundation for better stability and performance in the future.
By default, the Out-of-Process mode is disabled. If you experience any UI freezes or suboptimal typing experience, we recommend trying the Out-of-Process mode.
Advantages | Disadvantages | |
|---|---|---|
In-Process | Stable and tight integration with Visual Studio via the in-process IDE API | Heavy analyses can slow down the UI |
Out-of-Process | Performs heavy analysis tasks outside the Visual Studio process, eliminates UI freezes, keeps typing smooth, and resolves many performance issues |
You can always learn whether the Out-of-Process mode is enabled and quickly toggle it via the status bar indicator:
Toggle the Out-of-Process mode
Do one of the following:
In the main menu, select .
Go to the page of ReSharper options Alt+R, O, toggle the Run ReSharper in separate process checkbox, and then click Save and Restart.
Right-click the Out-of/In-Process indicator on the status bar and choose the corresponding action.
ReSharper will reinitialize without having to restart Visual Studio.
