When using “svcutil” with “/wrapped” parameter to generate client stubs from Corticon WSDL with full set of Corticon types, the entity attributes are not serialized when sending request

 

The reason .NET is not serializing Entity Attributes is because the code was not setting the AttributeSpecified property.
According to the documentation, svcutil generates the stub code this way when an attribute is mapped to an XML element that has minOccurs="0" in the WSDL.
The problem is with fields marked "Required" in Corticon. The WSDL for them has the attributes nillable="false" and minOccurs="0". This is not correct for a required field. 

Eg: CreditApplicationType App = new CreditApplicationType();
App.AnnualIncome = 15000;

And not

CreditApplicationType App = new CreditApplicationType();
App.AnnualIncome = 15000;
App.AnnualIncomeSpecified = true;

Corticon Entity attributes should not have the minOccurs property and should be rendered in WSDL like this: 
<xsd:element name="AnnualIncome" type="xsd:decimal" nillable="false" /> 

i.e Nillable should reflect the Required status of the Corticon Entity attribute: Required = Yes -> Nillable = false; Required = No -> Nillable = true.

The Corticon vocabulary today does not support default values, and, nillable=false minOccurs=0 implies use the default value if no values is provided.
Right now the WCF <fieldname>Specified values are required. Continue to use this value 

OR

Remove the minOccurs="0" setting  from the WSDL for the attributes that are required in Corticon, svcutil generates a stub that doesn't need the "Specified" property for every attribute.
