XmlArrayItemAttribute with IsNullable=true on collection of non-nullable elements

[bassem-mf]

Steps to reproduce:

Generate classes from the Authorize.Net XML schema file using the following command.

xscgen https://api.authorize.net/xml/v1/schema/AnetApiSchema.xsd

See the property GetMerchantDetailsResponse.PaymentMethods on line 10021.

[System.Xml.Serialization.XmlArrayItemAttribute("paymentMethod", IsNullable=true, Namespace="AnetApi/xml/v1/schema/AnetApiSchema.xsd")]
public System.Collections.ObjectModel.Collection<PaymentMethodsTypeEnum> PaymentMethods

IsNullable=true is not valid here because PaymentMethodsTypeEnum is not nullable.

The XmlSerializer constructor throws the following exception.

InvalidOperationException: IsNullable may not be 'true' for value type AnetApi.Xml.V1.PaymentMethodsTypeEnum. Please consider using Nullable<AnetApi.Xml.V1.PaymentMethodsTypeEnum> instead.

Does specifying --dnfin work for your use case?

[bassem-mf]

Yes! Adding the --dnfin option worked for me. Also, in my case, it was possible to just remove the IsNullable property manually after generating the classes. But I reported the issue to let you know in case you were not aware of it. And also for people searching the issues by the XmlSerializer exception message.

Thanks for the great software!
