I just found (and fixed) some bugs inside the XAML2CPP tool.
You can download the new release from here:

Changes history:
ver 1.0.0.1
- the application version is inserted in the generate files and written on the console
- the x:Name tag of the user control is used as class name instead of the XAML file name. If no x:Name attribute is specified the XAML file name will be used.
