Question

What is the correct way to accept sockets in a multi connection environment in .NET?
Will the following be enough even if the load is high?

while (true)
{
   //block untill socket accepted
   var socket = tcpListener.AcceptSocket();
   DoStuff(socket) //e.g. spawn thread and read data
}

That is, can I accept sockets in a single thread and then handle the sockets in a thread / dataflow / whatever.
So the question is just about the accept part..

Answer 1

Since I’m using Async CTP and DataFlow, the current code looks like this:

private async void WaitForSockets()
{
    var socket = await tcpListener.AcceptSocketAsync();
    WaitForSockets();
    incomingSockets.Post(socket);
}

Note that what looks like a recursive call will not cause stack overflow or block.
It will simply start a new awaiter for a new socket and exit.
