But what happens if you want to bind to a string representation of color? or you want to bind to a stroke dash property or path geometry? Whilst value converters are simple to implement, it is a shame that you have to create so many of them!A Universal Value ConverterWouldn't it be great to have a single value converter that has the same flexibility as the XAML parser? It is actually very simple to create such as converter (and after creating probably my 5th ColorToBrushConverter I have no idea why it took so long before I realised this!).. The NET framework has had an API for conversion between different types via TypeConverters for a long time.

The Fill property is actually of type Brush, and the XAML parser is performing some cunning type conversions in order to make the above markup work.. This converter can be used both within bindings and in code-behind to give more concise property setters.
