Lets say I wanted to make a game (Silverlight 2 based) and I want all my graphics to be vector based. I use Expression Design to make my graphics and export them as "Silverlight Canvas" XAML files. Now, because this is a game I'm making, I have no idea how many of each object would be on screen at a time, so these objects have to be added at run time. What is the best way to go about doing this? The XAML output from Design seems to just be a Canvas surrounding the other elements.
