Ignoring the fact that this is VB.NET ... Dead | X|

The outer loop only runs if an exception is thrown (and swallowed) outside of the inner loop's exception-swallowing Try..Catch block. Realistically, the only things that could trigger that would be the creation of the UdpClient, or the creation of the IPEndPoint. But that would mean that either the port was inaccessible, or the application had run out of memory. In which case, the next iteration would almost certainly throw the same exception again, leading to a thread constantly executing a tight try-throw-catch-try-again loop.

The receive call will allocate a new byte array. But there's no option to avoid that, and no way to make it reuse the same array. The only way that could be optimized would be if the BCL code did it for you. But that's unlikely, since it has no way of knowing what the caller will do with the returned array. So you'll have some GC churn on the inner loop.

If this is intended to implement a single instance application, there are far better ways to do that. For a start, in a VB.NET WinForms project, there's a specific option on the application properties to do this.
