count should be 1, but actually it's 2. When ConnectAsync returns false, Completed is not meant to be called.
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
SocketAsyncEventArgs e = new SocketAsyncEventArgs();
int count = 0;
e.RemoteEndPoint = new IPEndPoint(IPAddress.Any, 9999);
e.Completed += (sender, args) => Interlocked.Increment(ref count);
Debug.Assert(count == 1);
Could you provide a test case that demonstrate your issue?
A code snippet is not enough to fully understand what you're trying to do.
You want me to copy paste that code into a project for you? No thanks.
The problem is clear, if ConnectAsync returns false, it should not fire SocketAsyncEventArgs.Completed.
We've already worked around the problem.

Add a sample console project with the code from the report.
I ran it and count is 1, so I am not sure if I am using the correct mono version or if the test case is bad.
Mono 4.4.0 (mono-4.4.0-branch/fcf7a6d) (64-bit)
I ran the test on an iPhone, so it is possible that the network stack behaves differently when trying to connect to IPAddress.Any.
Created attachment 16875 [details]
Attached a new sample project that includes an iOS app project with the same code.
Both projects (console and iOS) reproduce the issue when using IPAddress.Any. The count is 2, and the expected is 1.
