## Unqualified {Binding}
The `{Binding}` usage shown in "Binding Expression Usage" creates a <xref:System.Windows.Data.Binding> object with default values, which includes an initial <xref:System.Windows.Data.Binding.Path%2A?displayProperty=nameWithType> of `null`. This is still useful in many scenarios, because the created <xref:System.Windows.Data.Binding> might be relying on key data binding properties such as <xref:System.Windows.Data.Binding.Path%2A?displayProperty=nameWithType> and <xref:System.Windows.Data.Binding.Source%2A?displayProperty=nameWithType> being set in the run-time data context. For more information on the concept of data context, see [Data Binding](/dotnet/desktop-wpf/data/data-binding-overview).

## Implicit Path
The `Binding` markup extension uses <xref:System.Windows.Data.Binding.Path%2A?displayProperty=nameWithType> as a conceptual "default property", where `Path=` does not need to appear in the expression. If you specify a `Binding` expression with an implicit path, the implicit path must appear first in the expression, prior to any other `bindProp`=`value` pairs where the <xref:System.Windows.Data.Binding> property is specified by name. For example: `{Binding PathString}`, where `PathString` is a string that is evaluated to be the value of <xref:System.Windows.Data.Binding.Path%2A?displayProperty=nameWithType> in the <xref:System.Windows.Data.Binding> created by the markup extension usage. You can append an implicit path with other named properties after the comma separator, for example, `{Binding LastName, Mode=TwoWay}`.

> In terms of dependency property precedence, a `Binding` expression is equivalent to a locally set value. If you set a local value for a property that previously had a `Binding` expression, the `Binding` is completely removed.
