	BeginCountOnlyQuery(AsyncCallback)	Initializes a cancelable asynchronous query that will return only the count of results by using a callback function.
	BeginLinkQuery()	Initializes a cancelable asynchronous query that will return a collection of WorkItemLinkInfo objects.
	BeginLinkQuery(AsyncCallback)	Initializes a cancelable asynchronous query that will return a collection of WorkItemLinkInfo objects by using a callback function.
	BeginQuery()	Initializes a cancelable asynchronous query of WorkItem objects.
	BeginQuery(AsyncCallback)	Initializes a cancelable asynchronous query of WorkItem objects by using a callback function.

	RunCountQuery	Executes a query that returns the number of results.
	RunLinkQuery	Executes a query that gets an array of WorkItemLinkInfo objects.
	RunQuery	Executes a query that gets a WorkItemCollection that contains WorkItem objects that satisfy the query.
	RunRegularQuery	Executes a query that gets an array of WorkItem IDs that satisfy the query.
