Fail to serialize: Referenced assembly cannot be found
dmiller opened this issue · comments
The failure of Assembly.GetReferencedAssemblies is hinted at here:
https://github.com/Lokad/ILPack/blob/master/src/Metadata/AssemblyMetadata.cs#L67-L74
In my case, the call to CreateType throws from
https://github.com/Lokad/ILPack/blob/master/src/AssemblyGenerator.Types.cs#L111-114 the error
Referenced assembly cannot be found: System.Linq.Expressions, [...]
In this case, the type is a class A derived from an abstract class B that implements System.Dynamic.IDynamicMetaObjectProvider, which is indeed in System.Linq.Expressions. Assembly.GetReferencedAssemblies does not see this reference, leading ultimately to an exception being thrown from AssemblyMetadata.GetReferencedAssemblyForType(Type type).
@dmiller Thanks a lot for taking the time to report this problem. We don't resources to push to this project at the moment, but don't hesitate to submit if PR if you can.
I was able to work around the problem in my application by having class A explicitly implement the interface that was causing the problem. Rewriting Assembly.GetReferencesAssemblies seems like a tall order, but a quick scan of types to pick up some missed assemblies might be possible.
Two more error reports coming -- Understood that you don't have time to deal with them. Just for the record and in case I can create fixes.
