Lukas, When you use ExtensionPart, it calls Assembly.Load on each file in the zip file referenced, so you don't need to do clr.Addreference.
System.Windows.Data.dll and System.Windows.Controls.Data.dll are not DLLs in Silverlight; they are in the Silverlight SDK. So you'll have to package them up into a separate zip file which you include in your AppManfest, just like you did with the SLToolkit.zip. ~js From: users-boun...@lists.ironpython.com [mailto:users-boun...@lists.ironpython.com] On Behalf Of Lukas Cenovsky Sent: Tuesday, March 23, 2010 5:42 PM To: users@lists.ironpython.com Subject: [IronPython] AddReference to Silverlight toolkit assemblies Hi all, I use Silverlight toolkit in my IronPython Silverlight app. To lower bandwidth, I put all necessary Silverlight toolkit .dlls into separate file called SLToolkit.zip which I reference in AppManifest.xaml: <Deployment.ExternalParts> <ExtensionPart Source="Microsoft.Scripting.zip" /> <ExtensionPart Source="SLToolkit.zip" /> </Deployment.ExternalParts> This works nicely if I don't need to reference assembly already existing in Silverlight - e.g. I do clr.AddReference('System.Windows.Controls.Data') and use DataGrid. Unfortunately, when I need to reference PagedCollectionView from System.Windows.Data, this approach does not work. Trying from System.Windows.Data import PagedCollectionView fails on ImportError: Cannot import name PagedCollectionView. Doing import System.Windows.Data System.Windows.Data.PagedCollectionView(some_data) fails with AttributeError: attribute 'PagedCollectionView' of 'namespace#' object is read-only. When I try to add clr.AddReference('System.Windows.Data') if fails with: IOError: [Errno 2] could not find assembly: System.Windows.Data (check the Web server). The only way how to make this work is to put System.Windows.Data.dll into .xap file and reference it with clr.AddReferenceToFile('System.Windows.Data.dll') from System.Windows.Data import PagedCollectionView Is there a way to make it work when System.Windows.Data.dll is in the separate file? Or should I use another approach? Thanks, -- -- Lukáš
