@weshaggard are you fine with that change? You can find the type here: https://github.com/dotnet/coreclr/blob/master/src/mscorlib/shared/System/UnitySerializationHolder.cs

And any idea why I didn't need a TypeForwardedFrom attribute on the UnitySerializationHolder? Is it because it sets the type itself with SerializationInfo.SetType(Type)?

Yes I'm fine with this change as it is along the lines as the other ones here. As for the TypeForwardedFrom question I'm not sure I would expect if you serialize on core it would end up with System.Private.CoreLib as the assembly it is from, is that not what is happening?

That's what's so interesting about it. It doesn't contain the QualifiedAssemblyName, so it's the optimized version without the attribute:

Interesting I don't know why that is. Your the expert here now :) My only guess is that the binary serializer omits assembly names for the core assembly? Not sure though. It is probably worth debugging though the code to understand further.

I have a guess but need to verify it. Thanks Wes :)
