Problem with generating WebService proxy using svcutil

Question

In our application we are forced to consume several WebServices. In the beginning we used just the \"Add Service Reference\" menu option, in order to create a WCF proxy.

Answer 1

I had to get rid of the use of "element" and much rather just used the "complexType"s.

So I removed the enclosing elements on the DataContracts and in the Messages, I set the type attribute instead of the element attribute. Now it works, thank you very much. :)

Answer 2

The schema used by the wsdl does not conform to the Data Contract Serializer's Schema Reference.

Problems:

1. "All elements must be qualified for a schema to be supported by DataContractSerializer".

   Your schema omits the elementFormDefault attribute on the tag so the default, "unqualified" is in effect. You need to add the following attribute name/value pair to the <schema> element so that the Data Contract Serializer (DCS) can resolve the local elements/types.

   elementFormDefault="qualified"

2. maxOccurs and minOccurs attributes on <sequence> tag must be 1 or omitted (default is 1).

   So, remove maxOccurs="unbounded" on the <sequence>.

3. Add maxOccurs="unbounded" on the <row> tag to get a nested collection data contract generated for the DataSet field.

   For example,

   <xsd:element name="DataSet"> <xsd:complexType> <xsd:sequence> <xsd:element name="row" minOccurs="0" maxOccurs="unbounded"/>

Answer 3

Hey I'm not sure how you generated your wsdl and stuff, but datasets has a few oddities.

When generating my proxy with a ds I need to reference this assembly:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Data.dll
