  3. The generated code opens in a separate AI Diff tab. Wait for the generation to complete. In the upper-right corner, select the way you want to review the suggested changes:

    • The Unified view shows the results in one editor.

    • The Two-Side view shows the results in two editors. The left side displays the original code. The right side displays the code with the suggested changes.

    Generated code in diff tab

    All changes are marked with different colors. Read more on how JetBrains Rider displays the changes in Compare files, folders, and text sources.

  4. If you want to improve the generated code, click Specify, add new requirements, and press Enter.

    AI Assistant will regenerate the code while taking into account the new specifications.

    If you want to regenerate the answer, click Regenerate.

  5. Click Accept all to insert the generated fragment to the rest of the code.

    To accept only part of the suggested changes, click the Accept button Accept in the Two-Side view or the Checkmark icon Accept in the Unified view on the line with the desired changes.

    Otherwise, close the AI Diff tab to discard all changes.

Enable name suggestions

When you rename (Shift+F6) a symbol, AI Assistant suggests name options for it based on its contents.

  1. While working on your code, press Enter to start a new line and wait for a few seconds to get a suggestion.

    The suggested code will be shown in gray font.
