Re: [Ikvm-developers] How to use the JNA through IKVM?

[Volker B. <vol...@go...>]

If you want use native method access then you need also the native part of IKVM. It is in the bin-x64 or bin-x86
directory. It depends on your platform.

Also it can be a good idea to add all dll of IKVM as reference if you have such problems. If you have it working then
you can remove the dlls that you not need. And test if it anyway run.
