The original targetNamespace from an XSD must be included in the resulting C# class

[SandGrainOne]

Description

The target namespace as defined by an XSD needs to be included when a model is serialized to XML. The generated C# classes must include a namespace assignment in the XmlRoot attribute that's decorating the class.

<xsd:schema 
  xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
  elementFormDefault="qualified" 
  attributeFormDefault="unqualified"
  targetNamespace="urn:no:altinn:message">
  <xsd:element name="Message" type="Message" />
  <xsd:complexType name="Message">
    <xsd:sequence>
      <xsd:element name="Title" nillable="true" type="xsd:string" />
      <xsd:element name="Body" nillable="true" type="xsd:string" />
    </xsd:sequence>
  </xsd:complexType>
</xsd:schema>

namespace Altinn.App.Models
{
  [XmlRoot(ElementName="Message", Namespace="urn:no:altinn:message")]
  public class Message
  {
    [XmlElement("Title")]
    [JsonProperty("Title")]
    [JsonPropertyName("Title")]
    public string Title { get; set; }

    [XmlElement("Body")]
    [JsonProperty("Body")]
    [JsonPropertyName("Body")]
    public string Body { get; set; }
  }
}

Considerations

Are there other ways to define a namespace? Most seres schemas do not have a target namespace.
