Dynamic web reference in a DLL

[Greg]

Hi,

I have a class library (DLL) that references a web service. This DLL is
referenced by web applications. The problem is, I need to reference a
development, test, or production version of the web service depending on
whether I'm in the development, test, or production environment. Is there a
way to dynamically change which version is referenced?

I found an article at Microsoft
(http://msdn2.microsoft.com/en-us/library/5k10s063(VS.80).aspx) that
describes how to do this if the web app references the web service directly,
but I can't figure out how to make it work when it's the DLL that references
the web service.

So is this even possible? Am I missing something obvious? I'm kind of a
web service novice.

Thanks!
Greg

ps. This is VS 2005, if that's important.

If you have a class library, then you probably have a class that references
the web service. Let the class expose a property which is the URL of the
service to reference. The consumers of the class library can set this
property before calling on methods that require the web service. The callers
should probably get the URL to use from a settings file.

Thanks! After I discovered how to generate a proxy class with wsdl.exe, this
solution worked perfectly.

Thank you!
