Re: Events

Jeroen,

Thanks,  reading this:

https://sourceforge.net/p/ikvm/mailman/message/4229204/

I was hoping that the definitions would work.

Any suggested work-around?  For whatever reason, we have a customer who 
can load IKVM dlls and any dlls we create using IKVM, but not the VS 
generated DLL.

There is some claim of requiring .NET 2.0 compatibility but is IKVM 
limited to the 2.0 API?

Thanks,

Jim
