Both console and service applications require common configuration steps.
Configuration can be changed by editing .config files of client applications ("bsds" section):
 <!-- BSDS Core configuration -->
  <bsds keyFilename="BSDS.key" tempFolder="tmp" deleteTempFilesOnExit="true"/>

The keyFilename option indicates file where Bing Maps key is stored (the first and only line of the file).
Following options allow specifying a folder storing temporarily generated files and
if it should be deleted on application exit. In most cases users will not need to change those parameters.
