The problem is that you are specifying that the request is cross-domain,
meaning that it will use the Script transport, but then you also specify
that you want a synchronous request, and the Script transport is not
capable of issuing a synchronous request.
Do you require a cross-domain request? If not, i.e., if the request for the
RPC is to the same server and port from which the page was loaded, you
should not specify setCrossDomain(true), which will then allow the
XMLHttpRequest transport be used, which does support synchronous requests.
Note that synchronous requests, in some browsers, lock up the entire
browser (all tabs, not just the one running this particular program) during
the whole time that the browser is awaiting the response from the server.
For this reason, synchronous requests a generally frowned upon.
If you do need cross-domain, and switch to async requests, be sure that
your server responds with the correct format of data, as specified in the
docs.

What is a .net service? What does it receive/send?
