Why does my binding show nothing and how do I debug it?

Beginner

Answer

Usually the BindingContext is null/wrong, the path has a typo, or the source doesn't raise PropertyChanged. Enable binding diagnostics/debug output, add x:DataType for compile-time checking, verify BindingContext, and confirm the property raises change notification. FallbackValue helps confirm the binding is evaluated.
<Label Text="{Binding Title, FallbackValue='NO BINDING'}" />
<!-- If 'NO BINDING' shows, the path/context is wrong -->
Real-world example A blank label is traced to a mistyped property name, caught instantly after enabling compiled bindings.
