[Ironpython-users] FW: IronPython WPF application

[Michael van der Kolff]

Hmm.  Perhaps you should have a look at the WPF example here:
http://www.ironpython.info/index.php/WPF_Example.  That one doesn't try to
load its UI out of an XML file.

There appear to be some tricks applicable to XAML with WPF, relating to
where you can load the XML from:
http://stackoverflow.com/questions/710329/load-external-xaml-file-using-loadcomponent

It seems that the XAML may be subject to an interesting variant of their
site-origin policy :(

Cheers,


Michael
