Code-Behind Switcher

Jump between a markup/design file and its code-behind, ViewModel, or other related file.

Mention

F7: go to the code file
Shift+F7: go to the markup file
Or right-click in the editor and choose View Code / View Markup (shown only when a counterpart applies).

If several related files exist (e.g. a XAML view with both a code-behind and a ViewModel, or .razor.cs and .razor.css), you pick one from a list.
