I don\'t know if you can do this, but basicly I need to be able to call a method in already running .NET process from a different assembly that don\'t share the same process.
Do you have control over the apps? If so, just have them 'open a channel' to each other. Perhaps you can just use a socket, to write to one from the other, or a named pipe, or something similar. It'd what I'd do, if I was writing both of them.
