Make auto-properties get-only
Starting from C# 6.0, you can define get-only auto-properties, which (similarly to readonly fields) can be only initialized via a constructor or an initializer. JetBrains Rider detects and helps you remove the redundant set accessor on auto-properties that are initialized from the constructor/initializer and have no write usages.
If you do not want JetBrains Rider to suggest this, you can disable the code inspection that detects it (Auto-property can be made get-only).
The reverse functionality is also available. If you decide to change the value of a get-only property later in your code (which leads to a compiler error), JetBrains Rider detects the error and suggests fixing it by adding the setter for the property:
Another option to make auto-properties get-only 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.
Remove setters from auto-properties that only have read access
Press Control+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 Make auto-property get-only, 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, refer to layer-based settings.
Select the scope where you want to make auto-properties get-only:
Place the caret anywhere in the file to make auto-properties get-only to the file.
Select one or more items in the Solution Explorer to make auto-properties get-only in the files under these nodes and their child items.
Press Control+R, C or choose from the main menu .
In the Reformat and Cleanup Code dialog that opens, select the newly created profile and choose another scope if needed. .
Click OK. JetBrains Rider will make auto-properties get-only in the selected scope.
If you want to make auto-properties get-only 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 Control+R, G. You can also create a custom cleanup profile that would combine making properties get-only with other code style tasks.
