I need to know that is it possible to use Google Maps (as a base map) and its GIS functionalities (like find/search features) in my web application developed with ArcGIS API for Silverlight/JavaScript.
Also I don't want to use ArcGIS server. I want to use open source GIS technology.

In the Google Maps/Google Earth APIs Terms of Service is specified that you must not access map tiles or imagery through interfaces or channels (including undocumented Google interfaces) other than the Maps API(s).
