Silverlight Viewer + drag-and-drop for .csv/.xls/.xlsx files

Idea created by jnowlin on Aug 7, 2012
    I would really like to be able to give my map user the ability to drag and drop a csv/.xls/.xlsx file with XY data (lat & long fields) into the viewer and have it insert as a layer.

    This ability is given on ArcGIS Online and with ArcGIS Explorer Desktop, so I would like these behaviors to be included with the Silverlight Viewer.
