A.
A Windows application that connects to a WCF service by using HTTP
B.
A Windows application that connects directly to a SQL Server 2008 database
C.
A Windows application that connects to a WCF service by using the proprietary protocol
D.
A Windows application that connects to a WCF service by using HTTP and persists data to a SQL
Server database
