At runtime, the process identifies the user agent, for example IE, Mozilla, etc. and then removes whatever is specific to Mozilla when the request comes from IE. A partial view is a chunk of HTML that can be safely inserted into an existing DOM. Most commonly, partial views are used to componentize Razor views and make them easier to build and update.

Instead, they rely on ViewData or ViewBag to pass data between controllers and views. While this offers flexibility, it sacrifices type safety, compile-time error checking, and IntelliSense support. Consequently, weakly-typed views are more prone to runtime errors and can be harder to maintain.
- This is one of the frequently asked ASP.NET MVC Interview Questions.
