The Bing Map Services provide search API, Geocode API, Reversed Geocode which we demonstrate in our Search
demos. I am not sure whether OpenStreet have similar Apis and we don't have such demos with OpenStreetMaps.
However, the good news is that BingGeocodeProvider can be used without BingProvider and you will be able to set OpenStreetProvider. I implemented this in the attached project based on our Geocode Demo. Just Double click on a street in the Map and the StreetNames below the clicked point will be shown in a MessageBoxes.
I hope this will help you proceed further.
