xaml Differences in the various XAML dialects Multi Binding
Example
Multi Binding is a feature exclusive for WPF development. It allows a binding to multiple values at once (typically used with a MultiValueConverter).
<TextBox>
<TextBox.Text>
<MultiBinding Converter="{StaticResource MyConverter}">
<Binding Path="PropertyOne"/>
<Binding Path="PropertyTwo"/>
</MultiBinding>
</TextBox.Text>
</TextBox>
Platforms other than WPF don't support multi binding. You have to find alternative solutions (like moving the code from view and converters to the viewmodel) or resort 3rd party behaviours like in this article: http://www.damirscorner.com/blog/posts/20160221-MultibindingInUniversalWindowsApps.html)
