Kay, This are a couple bad bugs in the current sources; we desperately need to have better test coverage on embedding IronPython in a C# Silverlight app (hopefully I'll get time for that next month). In the meantime, here are fixed, unsigned binaries: http://github.com/jschementi/orphanage/tree/master/embedding-ipy/Dependencies/. The IronPython and DLR sources should have the fix in the next couple days, and we'll discuss getting these fixes in for 2.6 RTM.
Michael, I finally tracked down what is causing your sub-directory module importing issue: http://blog.jimmy.schementi.com/2009/11/embedding-ironpython-in-silverlight.html In short, an empty file in the XAP file is the same as a non-existent file, so make sure your __init__.py file(s) are not empty. ~js > -----Original Message----- > From: users-boun...@lists.ironpython.com [mailto:users- > boun...@lists.ironpython.com] On Behalf Of Michael Foord > Sent: Tuesday, November 10, 2009 12:25 PM > To: Discussion of IronPython > Subject: Re: [IronPython] Fail to execute "import System" on Silverlight > embedded interpreter > > Kay Schluehr wrote: > > Hi IronPython list, > > > > I worked along Michael Foords introductory article about embedding > > IronPython in Silverlight together with his > > "EmbeddingIronPythonSilverlight" project documented here: > > > > > http://www.voidspace.org.uk/ironpython/silverlight/embedding_ironpytho > > n.shtml > > > > > > I added the following two lines to the source code > > > > source = pe.CreateScriptSourceFromString("import System", > > SourceCodeKind.Statements); source.Execute(scope); > > > > This worked all well with the given built and the shipped assemblies. > > > > Yesterday I downloaded the DLR dlr-34133, built it and replaced the > > assemblies of the "EmbeddingIronPython..." project with the latest > > SilverlightDebug ones.
