Description of problem:
Example application "csharp.example.server" has two optional arguments "url" (as the first) and "connectionOptions" (as the third). The second argument is omitted (it is reserved for an address and it is not used in this example). 

But when the example is started, the "connectionOptions" argument is not read without some senseless argument on the second position.

Current part of csharp.example.spout.cs:
...
static int Main(string[] args) {
            string url = "amqp:tcp:127.0.0.1:5672";
            string connectionOptions = "";

            if (args.Length > 0)
                url = args[0];
            // address args[1] is not used in this example
            if (args.Length > 2)
                connectionOptions = args[2];
...

Should be:
...
static int Main(string[] args) {
            string url = "amqp:tcp:127.0.0.1:5672";
            string connectionOptions = "";

            if (args.Length > 0)
                url = args[0];
            // address is not used in this example
            if (args.Length > 1)
                connectionOptions = args[1];
...

Version-Release number of selected component (if applicable):
qpid-cpp-win-3.22.36.1-1

How reproducible:
100%

Steps to Reproduce:
1. Unpack the qpid-cpp-win package and build C# examples.
2. Run a qpid broker with authentication requirement.
3. Try to run the server example: csharp.example.server.exe <broker_hostname> "{sasl-mechanisms:PLAIN,username:<user>,password:<password>}"

Actual results:
csharp.server.example cannot connect to the broker due authentication failure (the connection options are ignored).

Expected results:
csharp.server.example should be able to connect the broker.
