Add FindCity support

[vadimffe]

This is a great source of finding Country by Longitude and Latitude. Is there are possibility/intention of making this more detailed by adding cities?

Like it is now for country: LocationInfo countryResult = GeocodeService.FindCountry(location);

Would be great to have city support: LocationInfo cityResult = GeocodeService.FindCity(location);

All cities support maybe too much, but at least most major once.

Hi - that's a great idea. The one issue would be to get a datasource for the city's GPS boundaries. Unfortunately I don't currently have time to devote to this project, but feel free to fork and improve ;)
