I succesfully used this example in a Silverlight application. There was however one thing that I had to change.

Instead of raising the event and setting the new value, I had to set the new value and _then_ raise the event.

If if for instance editted a field in a datagrid bound to a property of a dynamically created object, it would change the displayed value back to the old value.

If you change
gen.Emit(OpCodes.Ldarg_0);
gen.Emit(OpCodes.Ldstr, pinfo.Name);
gen.Emit(OpCodes.Call, raiseEvent);
gen.Emit(OpCodes.Ldarg_0);
gen.Emit(OpCodes.Ldarg_1);
gen.Emit(OpCodes.Call, pinfo.GetSetMethod());
gen.Emit(OpCodes.Ret);
to:
gen.Emit(OpCodes.Ldarg_0);
gen.Emit(OpCodes.Ldarg_1);
gen.Emit(OpCodes.Call, pinfo.GetSetMethod());
gen.Emit(OpCodes.Ldarg_0);
gen.Emit(OpCodes.Ldstr, pinfo.Name);
gen.Emit(OpCodes.Call, raiseEvent);
gen.Emit(OpCodes.Ret);

it works like a charm!

I had little experiences with silverlight. but I setup a simple scenario
1) a WCF service that exposes all the functions needed to manage the Domain, all the objects are DTO.
2) I create a service reference from silverlight (This in turn creates proxy for the DTO that implements IPRopertyChanges
3) I setup silverlight application to work with dto, the user modify the objects, does operations and whenever he want he can press save.
4) The save button simply takes all the DTO and send them to the appropriate update function in the service.
5) The service does all the logic to update data.

Moreover silverlight runs in browser, and it does not have full trust, so certain operations are not permitted, I think code generation is one of these , but I have not tried.
