I've really enjoyed /IronPython In Action/, and have found it immensely helpful in my quest to understand integrating Python with WPF. (I'm something of a newbie.)

Unfortunately, I've hit a conceptual wall with Sliverlight. In particular, creating the *app.xap* file for the source code in *chapter13\13.1.3\ControlsExample1* seems to be hitting a roadblock. Here's the command I gave to Chiron from within the chpter13 directory:

*C:\Users\mfunke\Documents\Programming Reference\Python\Libraries\IronPython\IronPython In Action\sourcecode\chapter13>bin/Chiron /d:13.1.3/ControlsExample1 /z:app.xap*

Chiron gave me this feedback:

*Generating XAP C:\Users\mfunke\Documents\Programming Reference\Python\Libraries\IronPython\IronPython In Action\sourcecode\chapter13\app.xap from C:\Users\mfunke\Documents\Programming Reference\Python\Libraries\IronPython\IronPython In Action\sourcecode\chapter13\13.1.3\ControlsExample1*

I then moved *app.xap* from *C:\Users\mfunke\Documents\Programming Reference\Python\Libraries\IronPython\IronPython In Action\sourcecode\chapter13* to *C:\Users\mfunke\Documents\Programming Reference\Python\Libraries\IronPython\IronPython In Action\sourcecode\chapter13\13.1.3\ControlsExample1* and opened *index.html*. That's what generated the error in the attached screenshot.

Can anyone help me? How */should/* I be generating app.xap, and where should it live?

I'm running IronPython 2.6.1 for .NET 4.0, as well as .NET 4.0 (naturally) and Silverlight 4. Thanks in advance for any help you can give.


Hey Matt,

The IronPython in Action binaries include IronPython 2 (Python 2.5), which unfortunately isn't compatible with Silverlight 4 due to core-clr API changes (grrr). If you replace the IronPython binaries in the examples with the IronPython 2.6.1 "IronPython for Silverlight" binaries then all the code should "just work".

I need to update the examples and get Manning to use the later version - my apologies.

All the best,

Michael Foord
