This article demonstrates using C# and MapPoint 2009 to look up a street address from a latitude/longitude. MapPoint does not use a Web Service. All data is stored locally, on the user s machine. From my research, MapPoint provides the most economical solution to perform a reverse geocode locally. Libraries from vendors such as ThinkGeo or GeoFrameworks cost upwards of $3000 while MapPoint costs $300.
