In WPF or Silverlight application, the vectorial is king. It is for this reason that as soon as I can, I use a Path instead of a picture.
Therefore, you can have the same Path several times in the application. The temptation is strong to create a Style with a value in the Data property.
Unfortunately, there is a known bug with this property. When it is used in a style, the path is instantiated once. That is to say that if you have for example a list of item that uses the same style, only the first will be displayed. No error, but not the expected behavior.
