Proper way to use IntermediateSerializer with Pipeline Tool

Content Pipeline MGCB-Editor
8

Ok, for now I’ll use the class library technique.

I have found what seems to be a difference between Xna and Monogame. It is about deserializing multidimentionnal arrays. Maybe i’m missing something.

I got a simple class I want to serialize with a byte[][] array.

    public class Mask
    {
        public byte[][] array;
    }

Under Xna, I serialized it as:

<?xml version="1.0" encoding="utf-8"?>
<XnaContent>
  <Asset Type="Workshop01.Custom.Mask">
    <array>
      <Item>1 1 1</Item>
      <Item>1 1 1</Item>
    </array>
  </Asset>
</XnaContent>

And it was OK. But the monogame content pipeline does not accept it and gives me this error:

D:/[...]/workshop01/Workshop01/Content/Data/mask.xml: error: Importer 'XmlImporter' had unexpected failure!
Microsoft.Xna.Framework.Content.Pipeline.InvalidContentException: An error occured parsing. ---> System.Xml.XmlException: 'Element' est un XmlNodeType non valide. Ligne 6, position 8.

   … MonoGame.Framework.Content.Pipeline.Builder.PipelineManager.ProcessContent(PipelineBuildEvent pipelineEvent)

Lign 6 position 8 is the start of the second <Item>. It seems the </Item> is not accepted, so the second has no sense but I don’t know what to do about that. Is there an other way to serialize/deserialize multidimentionnal arrays ? Am I missing something ?

(The same question stands for int[][][] arrays.)
