Save and Revert Changes
JetBrains Rider automatically saves changes that you make in your files. Saving is triggered by various events, such as compiling, running, debugging, performing version control operations, closing a file or a project, or quitting the IDE. Most of the actual events are predefined and cannot be configured, but you can be sure that changes will not be lost as you work.

In the Settings/Preferences dialog Ctrl+Alt+S, go to .
Under Autosave, configure the following options:
