Re: Exchanging strings was: Windows Phone

There are many differences like that between the desktop .NET runtime and the Windows Phone .NET runtime.

If you rebuild IKVM from source you can add the ikvmc -noautoserialization option to the compilation of the OpenJDK assemblies (/ikvm/openjdk/openjdk.build), that should solve this particular issue.

Jeroen
