 ## dynamic_cast
 
-Use **`dynamic_cast`** when you cast an object (more specifically, a hat **^**) to a more derived type, you expect either that the target object might sometimes be **`nullptr`** or that the cast might fail, and you want to handle that condition as a regular code path instead of an exception. For example, in the **Blank App (Universal Windows)** project template, the `OnLaunched` method in app.xamp.cpp uses **`dynamic_cast`** to test whether the app window has content. It's not an error if it doesn’t have content; it is an expected condition. `Windows::Current::Content` is a `Windows::UI::XAML::UIElement` and the conversion is to a `Windows::UI.XAML::Controls::Frame`, which is a more derived type in the inheritance hierarchy.
