[Moonlight-list] Getting a basic IronPython SL app working in Moonlight

Tue Jul 21 21:00:59 EDT 2009

Hello Jimmy,

System.Windows.ExtensionPart is new in Silverlight 3 and used to refer
to external library packages (shared zip files). This feature does not
yet exists in Moonlight.

http://msdn.microsoft.com/en-us/library/system.windows.extensionpart(VS.95).aspx

However this is not used inside of your AppManifest.xaml so I guess*
you're shipping a new (3.0) assembly in your XAP file (which refers to
that type).

        * well a bit more than a guess since grep says your XAP's
        Microsoft.Scripting.Silverlight.dll refers to this type

Then again this message about System.Windows.ExtensionPart could be
unrelated to real issue** but you may wish to try with older (2.0)
assemblies to confirm this on Moonlight.

        ** but
        while http://jimmy.schementi.com/silverlight/sl-ipy-clock give
        me some output on SL2/XP - the only thing I get is the standard
        splashscreen followed by a TypeLoadException ;-)

TypeLoadException: Error 0x80131522.  Debugging resource strings are unavailable. See http://go.microsoft.com/fwlink/?linkid=106663&Version=2.0.31005.0&File=mscorrc.dll&Key=0x80131522
