How to delete records in CRM 2011 by query?

Question

I want to delete a set of entities in CRM 2011 by a attribute value. Ex. delete * from contacts where ContactId = "guid"...

How can I do this using the IOrganizationService?

You have two possibilities

Retrieve all records with a QueryExpression which you would like to delete. Iterate over this collection and call IOrganizationService.Delete for all of them.
You could run a BulkDeleteRequest which runs the deletion as a background task. See how to run a bulk delete or the Sample: Bulk Delete Records That Match Common Criteria
