Django has the Flatpages app, which lets site admins change content on specific pages without changing code. Flatpage content i stored in the database, sort of like in a CMS. Flatpages are typically used for about-pages and such.
Are there any good equivalents for ASP.Net MVC? I.e., a convenient way to manage page-content persisted to a database.
No.
Django seems closer to a CMS then "ASP.NET MVC" which is both a framework and just a general design pattern.
