I referred this above example, i dono much about wcf.

i am getting this error, could not start service host. HTTP could not register URL http://+8000/RegirstatorService/. Your process does not have access rights to this namespace namespace(see http://go.microsoft.com/fwlink/?LinkId=70353 for details).

can anyone help me out please?

Thats a fairly standard thing you need to do to get wcf running. Log in as admin then run netsh http add urlacl url=http://+:80/MyUri user=DOMAIN\user (as the msdn doc says).

That then give you permission to use the namespace in future and it should all work fine

Edit: also giving you an up vote to counteract the down. There was plenty of info to ansewr the question
