Re: [Ikvm-developers] DeclaringTypeWrapper is only available for finished types ?

[Jeroen F. <je...@su...>]

Hi,

This is an IKVM bug. It is unrelated to IKVM.Reflection. The runtime is trying to reflect on a class that has not been fully compiled yet.

If you know what types are involved, you can work around the problem by forcing the types to be compiled using Class.forName("...").

I will fix this in the next development snapshot.

Regards,
Jeroen
