Type: System.Boolean true if the Socket allows only one socket to bind to a specific port; otherwise, false. The default is true for Windows Server 2003 and Windows XP Service Pack 2, and false for all other versions.
If ExclusiveAddressUse is false, multiple sockets can use the Bind method to bind to a specific port; however only one of the sockets can perform operations on the network traffic sent to the port. If more than one socket attempts to use the Bind(EndPoint) method to bind to a particular port, then the one with the more specific IP address will handle the network traffic sent to that port.
If ExclusiveAddressUse is true, the first use of the Bind method to attempt to bind to a particular port, regardless of Internet Protocol (IP) address, will succeed; all subsequent uses of the Bind method to attempt to bind to that port will fail until the original bound socket is destroyed.
