By navigating to Tools > Options > Text Editor > C# > Code Style > Naming, you can create a custom naming style (e.g., adding an underscore prefix, camelCase) and apply it to private or internal fields, so auto-generated dependencies like IMyDependency become _myDependency instead of myDependency. ## Full article daily.dev links to this article rather than hosting it.
