Rider is ordering my variables by name...

Hello Joao,

Thank you for contacting JetBrains Support. 

The behavior you’re observing is due to Rider’s File and Type Layout feature, which automatically reorder C# code elements (like fields, properties, and methods) based on predefined patterns.

How to Customize or Disable This Behavior

1. Disable Layout During Code Cleanup

• Option A: Avoid using the “Full Cleanup” profile (which includes file layout).
• Option B: Create a custom cleanup profile: Duplicate an existing profile, then uncheck “Apply file layout”.

2. Modify the Default File Layout

• Navigate to File | Settings | Editor | Code Style | C# | File Layout
• To disable reordering entirely, load an empty pattern (no rules).

3. [Advanced] Create a Custom Layout

For granular control, follow Rearrange members with file and type layout patterns⁠⁠⁠⁠⁠⁠⁠ to create a custom file layout as you prefer. For example, the settings below will sort fields based on access modifier: 

   <Entry DisplayName="Private instance fields">
            <Entry.Match>
                <And>
                    <Kind Is="Field" />
                    <Not>
                        <Static />
                    </Not>
                    <Access Is="Private" />
                </And>
            </Entry.Match>
            <Entry.SortBy>
                <Readonly />
                <Name />
            </Entry.SortBy>
        </Entry>
        <Entry DisplayName="Protected instance fields">
            <Entry.Match>
                <And>
                    <Kind Is="Field" />
                    <Not>
                        <Static />
                    </Not>
                    <Access Is="Protected" />
                </And>
            </Entry.Match>
            <Entry.SortBy>
                <Readonly />
                <Name />
            </Entry.SortBy>
        </Entry>
        <Entry DisplayName="Internal instance fields">
            <Entry.Match>
                <And>
                    <Kind Is="Field" />
                    <Not>
                        <Static />
                    </Not>
                    <Access Is="Internal" />
                </And>
            </Entry.Match>
            <Entry.SortBy>
                <Readonly />
                <Name />
            </Entry.SortBy>
        </Entry>
        <Entry DisplayName="Public instance fields">
            <Entry.Match>
                <And>
                    <Kind Is="Field" />
                    <Not>
                        <Static />
                    </Not>
                    <Access Is="Public" />
                </And>
            </Entry.Match>
            <Entry.SortBy>
                <Readonly />
                <Name />
            </Entry.SortBy>
        </Entry>

Please note that Rider currently does not provide a friendly UI for creating and validating file layouts. This feature is tracked under RIDER-29621 user friendly UI for File Layout (designer). 

Please let me know if you have any further questions.
