Is it available?
I tried using IKVM(http://www.ikvm.net/), but there were so many warnings. And I am unable to use the generated dll
It should be soon available in maven repositories thanks to Sonatype services.
For the impatient:
Thanks to Jeroen Frijters we'll be having soon the dlls that can be used in .net with the IKVM runtime. Check http://www.ikvm.net/ for more details.
