Use auto-properties

Last modified: 11 February 2024

Auto-implemented properties (also known as 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.

By default, JetBrains Rider highlights most of the properties that could be converted to auto-properties and suggests the corresponding quick-fix or fix in scope:

Use auto-property quick-fix

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:

To auto-property context action

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 Built-in: Full Cleanup profile or create and run a custom profile solely targeted at your specific task as described below.

If you want to convert properties to auto-properties without opening the Reformat and Cleanup Code dialog to choose a profile, you can bind the created profile to the silent cleanup and run it by pressing Ctrl0E,0F. You can also create a custom cleanup profile that would combine converting to auto-properties with other code style tasks.

You can convert properties to auto-properties in code that you have recently modified and are going to commit to Git. JetBrains Rider will run the selected cleanup profile before committing.

You can convert properties to auto-properties every time you save changes in a file to make sure that your edits always comply with your code style. Note that this will only happen when you save changes explicitly with Ctrl0S or CtrlShift0S and will not be triggered by auto-saving. However, all auto-saved files are placed to the 'reformat and cleanup' queue and will be processed on the next explicit save.
