I'm a .NET developer, working in the industry and also developing open source software, mostly in the OpenStreetMap and GPS arena.

• Kosmos - older version of Maperitive: http://igorbrejc.net/kosmoshome
• GroundTruth - generates Garmin GPS maps from OpenStreetMap data: http://wiki.openstreetmap.org/wiki/GroundTruth
