I'm pleased to introduce my first application for the NXT created with Microsoft's Robotic Studio: a GUI-based remote control, running on the PC (XP only) and commmunicating via Bluetooth with the brick (or nearer the mark: with the LEGO NXT motor services running there).
It's very simple still, containing buttons only for running each motor separately (at need concurrently) forward or backward and for stopping them, but with the fact in mind that I'm a newbie to C#, the Visual Studio and to the Robotics Studio, I'm happy that it works at all now (after all the rummaging of the tutorials, the samples' code and a bunch of manifest files - the NXT parts are still pretty scantily documented).
Once I have spiced up the app and found out how to package Robotics Studio services for delivery, I'll put the whole stuff on my web page.
At interest, though, I could post some illustrating code snippets here already.
Regards,
Matthias Paul
