Hi Sherif / Rob,
The Virtuoso ADO.Net Provider DBcommand class has a detault CommandTImeout
property value of 30 seconds, as detailed at:
http://docs.openlinksw.com/virtuoso/virtclientref.html#vcrvirtuosocommandclassWhich would be the timeout you are hitting, so does the dotNetRDF library allow this property value to be set so it can be increased as required ?
