Hello all,

I am new to .NET and web services so any guidance is appreciated!

I have created a (C#) web service the .NET way, creating the code
first and having .NET auto generate the WSDL.  This was pretty
straightforward, and after adding a few atrributes to clean up the
SOAP requests and responses, I have a nice interface.

Now, what I want to do is lock down the interface (WSDL) and code to
that, not the other way around.  So, I grabbed a copy of the WSDL and
started a new solution.

I have two projects, one a simple project that builds the abstract
class for the webservice (WSDL /Server), and the other which includes
the .CS from that.  I then derive from this base class and implement
my service.  I have copied all of the attributes and prototypes
straight from the base class.  I have changed the namespace/class
structure to more accurately represent the final resting place for
this service.

Now, when I add a test project and attempt to add a Web Reference to
my service, it fails.  I select my .WSDL through localhost, and the
response is "The specified module could not be found".  I have no idea
what the real problem is here, but the IIS log is showing two entries,
401 then 500 for the WSDL.  I'm not sure what authorization problem I
am having to access the WSDL, and I don't know how to find any details
beyond this message.

Do I still need an ASMX page, or is this irrelevant now that I am
working from the WSDL?

Does anyone know of some tutorials on doing this kind of thing?  All I
can find are articles based on code --> interface for .NET, now the
other way around.

I really hope that I can do this, because I want to have my interface
locked down and I will soon need to deal with nillable value types :-(

Thanks for any help you can give!
