Web Reference calls Serializable which won't compile

[Stefan Barlow]

After I assign a web reference to my C#.net web service within my Pocket PC
project, when I compile I get the following errors. The problem is when I
generate the web reference, it uses these classes which apparently are not
available for the CF? Why would it generate code referencing unavailable
clases that won't compile for my web service, but not for other services I
tried?

missing a using directive or an assembly reference?)
