We're&nbsp;trying&nbsp;the&nbsp;evaluation&nbsp;version&nbsp;of&nbsp;Geocoder&nbsp;and&nbsp;run&nbsp;into&nbsp;the&nbsp;exception&nbsp;"The&nbsp;given&nbsp;key&nbsp;was&nbsp;not&nbsp;present&nbsp;in&nbsp;the&nbsp;dictionary"&nbsp;when&nbsp;calling&nbsp;GeocoderMatch.GetCentroidWkt().&nbsp;&nbsp;The&nbsp;NameValuePairs&nbsp;collection&nbsp;has&nbsp;an&nbsp;entry&nbsp;for&nbsp;"CentroidPoint"&nbsp;with&nbsp;a&nbsp;value&nbsp;of&nbsp;"POINT(-87.674574&nbsp;41.9633400000002)"&nbsp;which&nbsp;I&nbsp;thought&nbsp;would&nbsp;be&nbsp;used&nbsp;in&nbsp;the&nbsp;GetCentroidWkt()&nbsp;method&nbsp;call.&nbsp;&nbsp;Is&nbsp;that&nbsp;not&nbsp;correct?

Note&nbsp;that&nbsp;we&nbsp;can&nbsp;successfully&nbsp;create&nbsp;a&nbsp;PointShape&nbsp;using:

new&nbsp;PointShape(geocoderMatch.NameValuePairs["CentroidPoint"])

with&nbsp;the&nbsp;WKT&nbsp;listed&nbsp;above.
