I thought I would update this thread by pasting in C# JEXEServer code that
compiles and works just fine in the free Express 2008 Edition of C#.
The trick to getting this to work is to only create one instance of the
JEXEServer and let the C# garbage collector cleanup. This snippet of code
lacks the general approach of Alex Rufon's class but is so simple that
anyone can follow and use it.
Cheers
