Well the Assembly type is marked with the SerializableAttribute so I was
presuming to try something naive like a BinaryFormatter. This certainly
doesn't blow up when you try it. Hmm... how to go from a binary format
to a real assembly on disk is another question. Saving it as a file that
can be deserialized back into an assembly object seems plausible but
this isn't quite the same.
I guess a full IL writer would be needed - which means back to Cecil and
the like and seeing if parts of them could be run on Silverlight. *sigh*
I'll look at ildasm...

I'll start with ildasm. I looked at Cecil but it was a bit low level.
I've also been looking into the CompileModules source code. It doesn't
look impossible to get this actually working on Silverlight and
serialize out rather than try to save to disk (ScriptCode and
ScriptCode.SaveToAssembly are all public where a lot of the work is
done).
I'll try ildasm first.

I can only assume this exception is coming from having the assembly
identities being different - but it's strange because it does seem to
be looking in the 2.0.5.0 assembly, which is Silverlight, and the type
is definitely in there. Hopefully re-writing the binaries will make
this go away.

In theory there's just 1 IL re-write that's required for this to
work. And that should be replacing the references to
mscorlib/IronPython to point at the Silverlight versions. There's
no
way to directly have the written binaries target Silverlight because
Reflection Emit has no cross-compilation support :(.
I need to rewrite references to the IronPython / DLR assemblies to
use
the Silverlight versions and the same for mscorlib.
Any pointers as to how I should start?
Do you know what's happening when trying to import packages?

Subject: [IronPython] Compiling with Pyc for Silverlight
Hello guys,
I'd like to modify Pyc to work with Silverlight. I tried it with
simple
modules and it works straightforwardly - but I have a report that
it
doesn't work with packages.
I'll try it - but if anyone has any idea of how to modify the
bytecode
generation to target the CoreCLR it would be appreciated. As far
as
I
can tell from looking at the source it isn't adding any direct
references to the desktop assemblies. Any clues as to what changes
I
should make? (Other than running from Silverlight and serializing
the
generated assemblies from memory to base64 which I would prefer to
avoid...).
Michael
