What does Section already defined mean and how to fix it?

Answer 1

The page structure is usually set in the _Layout.cshtml file (can be set directly in the view or controller), which sections can/should be rendered and where (@RenderSection("scripts", required: false)). When rendering a page, a section with the same name cannot occur more than once. You probably have a section definition (@section Menu) multiple times. Check which Layout is being used, which sections are defined there, and whether those sections are repeated in the Layout, View, and Partial View used when rendering this page.
