I am pretty new to programing and need help compiling the
proxy for my WebService in C#.

I have been going through a book on WebServices and am at
the part where I need to compile my proxy into a .NET
Assembly.  However, I am getting a CS0006 error.

Here's what I am typing:
-----
csc.exe /out:bin\pmcalc.dll /target:library /reference:syst
em.xml.serialization.dll /reference:system.web.services.dll
pmcalc.cs
-----

I get the following error:
-----
error CS0006: Metadata file 'system.xml.serialization.dll
could not be found
-----

I've looked and I don't have the
system.xml.serialization.dll file in my system even though
I have the 1.1 Framework and SDK.  

Is there a new way to do this in the 1.1
Framework?  ...becuase EVERYTHING I read says to do it the
way that I have been doing it.

Need Help!

Thx - Jack
