XML Serialization problem after migrating from 2.0.792 to 2.0.805 and 2.0.810

[anoordover]

After migrating my code-generation from 2.0.792 to 2.0.805 and 2.0.810 I get the following stack-trace when serializing my objects. Of course I want to help to solve this issue but I don't know where to start. I can't change the xsd's I use for code-generation (provided by an external party).

Might this be a problem:

<complexType name="PGPDataType"> 
  <choice>
    <sequence>
      <element name="PGPKeyID" type="base64Binary"/> 
      <element name="PGPKeyPacket" type="base64Binary" minOccurs="0"/> 
      <any namespace="##other" processContents="lax" minOccurs="0"
       maxOccurs="unbounded"/>
    </sequence>
    <sequence>
      <element name="PGPKeyPacket" type="base64Binary"/> 
      <any namespace="##other" processContents="lax" minOccurs="0"
       maxOccurs="unbounded"/>
    </sequence>
  </choice>
</complexType>

Duplicate with #378?

[mganss]

Yes, this is the same issue as #378. Although you might not be able to change the upstream XSD, perhaps you can create an XSD as described in #378 (comment) just for the purpose of creating C# code. The resulting code will be able to deserialize XML documents that comply with the original XSD. If you want to serialize also, you just have to make sure that either one of PGPKeyId or PGPKeyPacket is non-null to comply with the original schema.
