Auto-implemented properties (also known auto-properties) allow declaring type properties that do not have additional logic in a simpler way. By default, JetBrains Rider encourages using of auto-properties when possible, but this behavior is configurable.
If you do not want JetBrains Rider to suggest this, you can disable the code inspection that detects it (Convert property to auto-property). In this case, properties with backing fields are not highlighted and quick-fixes are not suggested, but you can still apply the conversion with the context action or with the corresponding refactoring:
The reverse functionality of converting existing auto-properties to properties with backing field is also available with the corresponding context action. You can also generate default bodies for property accessors using the To computed property context action:
Another option to convert properties to auto-properties in a bulk mode is code cleanup. You can either run code cleanup with the default Default: Full Cleanup profile or create and run a custom profile solely targeted at your specific task as described below.
Convert properties to auto-properties with custom code cleanup profile
Press Ctrl+Alt+S or choose(Windows and Linux) or (macOS) from the menu .
Go to the cleanup profiles settings page:.
Create a new profile as described in the Create a new custom cleanup profile section. In the Selected profile settings section for the new profile, tick the Use auto-property, if possible checkbox. Optionally, you can enable other code cleanup tasks in this profile.
Click Save in the Settings dialog to apply the modifications and let JetBrains Rider choose where to save them, or save the modifications to a specific settings layer using the Save To list. For more information, see Layer-Based Settings.
Select the scope where you want to use auto-properties:
Set the caret anywhere in the file to use auto-properties to the file.
Select one or more items in the Solution Explorer to use auto-properties in the files under these nodes and their child items.
Choose Code | Code Cleanup in the main menu.
In the Code Cleanup dialog that opens, select the newly created profile.
Click OK. JetBrains Rider will use auto-properties in the selected scope.
