The optimal solution for this task is a view component (https://www.learnrazorpages.com/razor-pages/view-components). You create a class that inherits from ViewComponent e.g. MenuViewComponent, and inject your context or data service into the constructor, and use it in an InvokeAsync method to generate a model that it passed to the view. The view is a simple razor file named default.cshtml located at /Pages/Shared/Components/<component name>/, where <component name> in this example is Menu.
