I know that passing variables "ByRef" to a web web service is permitted, but
what I am expreriencing is quite odd.

If I take out my ByRef parameter from the method of my web service, i can
step through (F11) into the web service for debugging.

If I put in a ByRef parameter in the method of the web service, F11
(stepping into the method) does not work. It acts as though I hit the F10
key (Step Over).

Has anyone else seen this?

Thanks,

Generally ByRef parameter does not make any sense in web service world. All
parameters are passed by value. Honestly I do not know what is happening. Go
to the web service proxy class and see what is it calling.

It's not entirely true when you say all the parameters are passed by
values, since web services define input and output messages element in
WSDL in such a way that it's always XML element fragment. You can of
course make input and output messages refer to the same element, but
this won't necessarily make them reference type. This must be
implemented by the web services framework(i.e. ASP.Net web services,
axis etc.)
