Passing interface as parameter in web service???

[Kevin Yu]

hi all

is there a way to pass an interface as input parameter for a web method?
since interface is not serializable, does that mean it's impossible to do
that?

In the sense that WSDL defines an interface, and that a web method can
be designed to use that interface on the fly ( I know because I've built
such a thing )...yes.

How?

please show some code sample.

This code will generate the web services interface from a WSDL
dynamically. This code requires the ThinkTecture 1.5 libraries (
available free at thinktecture.com ).
