WSDL generates with wrong "minOccurs" values

[joewhitehair]

Using the XSD.exe tool, I created a number of classes from my XSD file.
When I generate the WSDL for my web service, the schema does not have
the proper Occurance constraints for the attributes. In this example,
the MessageID element should always occur (minOccur=1, maxOccur=1), but
the WSDL generates minOccur=0. I can't pinpoint why this is happening
and I
can't find a may to force this in the code either. Anyone have any
insight? This is happening with a large number of elements, I just
provide one example below.

Code of the schema, classes, and WSDL excerpts below.

Thanks.

can you better explain what it is that you are doing,
and what you get,
and what you expect to get?

It seems you start with a WSDL that has minOccurs="1" and maxOccurs="1" on
some number of elements.
Then you generate VB code from that. Everything looks fine.
Then what? do you then generate WSDL from that (generated) VB code? and
that WSDL is the problem? if so, Why generate it? Why not use the
original WSDL ?

It seems pretty clear to me!
There is no .Net attribute for controlling the min/maxoccurs schema
attribute, is it?

So when you declare public fields that are reference types
and then generate a schema definition from the class definition you get all
these fields
with minoccurs="0" which means that they are optional.
It happens even for string fields which is quite rudiculus! I have a bunch
of classes
with string fields are not optionall at all.
How do you force the minoccurs=1 for thes type of fields?
