Is there a way to serialize my objects to XAML in Windows Store applications?

What do you mean by serialize to and deserialize from XAML? It would help if you could provide more clear examples of what you are trying to do.

There is a XamlReader class which can load a Xaml fragment into an object tree. There is no analogous writer, but you can serialize and deserialize your data objects to XML and rebuild a Xaml tree based on that.
