*sigh*
You just want to change the references to an assembly from the desktop
version to the SL version? With Cecil it's like:
var assembly = AssemblyFactory.GetAssembly (file);
foreach (var reference in assembly.MainModule.AssemblyReferences) {
if (!IsTargetAssembly (reference))
continue;
reference.Version = new Version (2, 0, 5, 0);
}
AssemblyFactory.SaveAssembly (assembly, file);
Now it doesn't guarantee that the resulting assembly is coherent,
visibility wise, as you may have used methods that are not visible or
not existent in SL.
Thanks for that - if it would work it would be really useful, however...
I think I've done the equivalent of this using ildasm / ilasm. I've
disassembled the assembly to IL, then replaced the references with the
references to Silverlight assemblies and re-assembled.
The resulting assembly throws exactly the same error - which makes me
think that the assemblies compiled by Pyc are using things that aren't
available in Silverlight. *However* -
Microsoft.Runtime.CompilerServices.StrongBox does exist in
Silverlight. I think I'll try the whole process again just to see. My
guess is that rewriting would require an intimate knowledge of the
differences between the CoreCLR and standard .NET.
No - I've rerun the whole process from compiling with Pyc through to
replacing the references in the il and reassembling. Same error. Shame.

I can't import it in a Silverlight application though (the following
code does work on the desktop version of IronPython):
import clr
clr.AddReference('Microsoft.Scripting')
clr.AddReference('Microsoft.Scripting.Core')
from Microsoft.Runtime.CompilerServices import StrongBox
ImportError: No module named Runtime
