What is the difference between the two asynchronous forms? Which has better performance handling sockets and handling thousands of connection simultaneously?
Example for Beginxxx: http://msdn.microsoft.com/en-us/library/5w7b7x5f(v=vs.110). aspx
Example for Xxxasync: http://msdn.microsoft.com/en-us/library/system.net.sockets.socketasynceventargs.aspx

None. One was made to meet an asynchronous programming "standard" and the other.
Behold: http://msdn.microsoft.com/en-us/library/jj152938(v=vs.110). aspx
The first "Begin" is to meet the APM (Asyncronous Programming Model) and the second (Blahblahblahasync) to meet the TAP (Task-based asyncronous Pattern). Tasks is newer and simpler to use.
On time, on my blog: http://ericlemes.com you find examples of server socket with both scenarios and some explanations on the gains obtained with asynchronous I/O in general.

In terms of performance, both are equal, the connection is always made using the class "Socket".
But in the example of Beginxxx, it is a simpler solution, using the basic form of the use of Async.
In the case of Xxxasync is an event-based example, this example is more complete because in this example it already expects up to 100 simultaneous connections as can be seen in this line:
listenSocket.Listen(100);
For description of what you need, you could use any of these solutions, however the Xxxasync is already closer and prepared for what you want, note that it is already an example of a server, just implement the desired actions.
Now, depending on what you’re going to do, and who you’re going to consume, you can eliminate several network layer concerns using WCF or even Webapi. But there will depend on the requirements of the project.

It’s interesting because I read in the documentation that Async is an improvement over Begin.
