I get an error:

The tag 'PercentToPixelsConverter' does not exist in XML namespace 'clr-namespace:Converters;assembly=TestBA'.

Answer 1

You will need to make your class public:

public class PercentToPixelsConverter

Answer 2

You don't have to specify assembly name if the namespace is from the same project or assembly :

xmlns:c="clr-namespace:Examples.Bootstrapper.Converters"
