I have created shapefiles now which is basically a couple of polygons representing rooms in a building. They appear fine in QGIS, but when I try and load it into the application (RadMap in Silverlight) the screen just goes blank.
Anybody have any experience with this?
EDIT: I'm using QGIS and have tried MapWindow too and the shapefile CRS is set to the recommended 'EPSG:4326 - WGS 84'. When I drew the polygon I made sure the scale was set to 1:1 in the hope of eliminating the possibility that the shape is just to small to see when it renders in RadMap/Silverlight.
