The Net.Leksi.WpfMarkupExtension library is designed to extend WPF markup. It contains several classes that you may find useful when developing XAML. All classes are contained in the Net.Leksi.WpfMarkup namespace.

• StyleCombiner - allows you to apply multiple styles to an element without inheritance.
• ParameterizedResource - analogue of StaticResourceExtension, which allows using resources with parameters that can be replaced with different values in the markup.
• XamlServiceProviderCatcher - allows using ParameterizedResource in code.
• BindingProxy is a universal resource that can serve as a link to any object or act as a binding.
• BindingProxyMarkup - used when you need to place a binding value where a markup extension is required.
• IUniversalConverter - combines the System.Windows.Data.IValueConverter and System.Windows.Data.IMultiValueConverter interfaces for convenience.
• DataSwitch - used instead of a large number of DataTrigger that have the same binding but different trigger values. Reduces both the XAML text and the number of calls to the binding source.
• BoolExpressionConverter - incomplete implementation of the IMultiValueConverter interface, which implements the object Convert(object[] values, Type targetType, object parameter, CultureInfo culture) method, which is passed an array of bool values values and a string describing the Boolean expression above them, as parameter. Returns the result of evaluating an expression.
• ConverterProxy - an adapter that is a MarkupExtension for converters IValueConverter or IMultiValueConverter, which are not MarkupExtension and cannot become one, since they are already inherited from another type, but are required there, where MarkupExtension is expected.
