Quick-fixes for code issues

Last modified: 07 April 2022

JetBrains Rider helps you instantly repair most code issues that it detects in design time. It is as simple as pressing Alt+Enter at a highlighted code issue and choosing the appropriate way to fix the problem or improve the suboptimal code.

Apply quick-fixes

Quick-fixes are visually displayed as action indicators to the left of a highlighted code issue. These indicators appear when you set the caret at the code issue. The following indicators imply quick-fixes:

Themed icon red bulb screen gray

Suggests a quick-fix for the detected code issue with the Error severity level.

Themed icon refactor this screen gray

Suggests an inplace refactoring or a refactoring that can fix the detected code issue.

Themed icon yellow bulb screen gray

Suggests a quick-fix for the detected code issue with Warning, Suggestion or Hint severity level.

View and apply quick-fixes

  1. Use the issue highlighting in the editor and the error stripe to navigate to a specific code issue.

  2. Set the caret at the highlighted issue.

  3. Press Alt+Enter or click the action indicator to the left of the caret to open the action list.

  4. Click the desired quick-fix or select it using arrow keys and then press Enter.

In most cases, a quick-fix is applied immediately. However, some quick-fixes (for example, Change All) require user interaction to choose how exactly they transform your code. In these cases, a Hot spot session is deployed in the editor, where you can select one of the suggested values or provide your own values in the active input positions:

Hot spot session after applying quick-fix

To complete the hot spot session:

  • If JetBrains Rider suggests some values for the current parameter, use Up and Down arrow keys to navigate through the list of suggested values, or just type in a desired value.

  • Press Tab or Enter to accept the value and move to the input position of the next parameter. If this is the last parameter, the hot spot session completes and the caret moves to the end position defined for the session.

  • Press Shift+Tab to move the input focus to the input position of the previous parameter.

  • Press Esc to exit the hot spot session. In this case, all session parameters will be initialized with default values.

Some quick fixes can be applied not only in the current caret position, but in a larger scope. For more information, see Fix in scope.
