To write a nice network port scanner you need packet level
access which C# does not provide ... (or so I understood)..
IIRC the `ACK Catcher' is the fastest scanning idea ...

Otherwise port scanning can be done using a worker pool of 
say 10 threads and a connect & try/catch to the port ...
This is a crude method ... IMHO ...

Or if you have an even better idea , enlighten us please ..
