Description of problem:
C# examples packed in the qpid-cpp-win package, "csharp.example.helloworld", "csharp.example.declare_queues", "csharp.direct.sender", csharp.direct.receiver, csharp.example.server" and "csharp.map.receiver" cannot run. These clients create a connection without "connection options" and the connection cannot be created; the clients raises an exception, see below, please:

C:\qpid_VS2008\bin\Release>csharp.direct.sender.exe <broker_hostname>
csharp.direct.sender
host : <hostname>
addr : amq.direct/key
nMsg : 10

2015-02-23 10:39:25 [Client] warning Broker closed connection: 320, connection-forced: Not authenticated!
Exception Org.Apache.Qpid.Messaging.QpidException: connection-forced: Not authenticated!

Version-Release number of selected component (if applicable):
qpid-cpp-win-3.22.51.1-1 with qpid-cpp-0.22-51 (on the broker)

How reproducible:
100%

Steps to Reproduce:
1. Install, configure and run a qpid broker with disabled authentication (set "auth=no")
2. Download, unpack and compile the qpid-cpp-win packages.
3. Try to run one of the C# examples mentioned upper, f.e. "csharp.direct.sender"

Actual results:
The client fails with the exception because no connection can be created (see upper, please).

Expected results:
The client should connect the broker without exceptions.
