Copying custom objects through Clipboard

[fabianoriccardi]

I would copy and paste a custom object between 2 instances of the same app, and I'm looking for simplest way, so, if possible, I would avoid "manual" serialization.

In WPF and Winform it was fine since I can use Clipboard.SetDataObject(), IDataObject in combination with Serializable attribute on my custom class (here an example). But in Windows App SDK, using DataPackage, I cannot find a similar alternative, and the only working method is the serialization in JSON (or whatever other char-based format) and passing the custom object as a simple string.

Is there a similar API in WASDK as the ones present in WPF and WinForms?

I had tried the following:

[Serializable]
public class Person
{
    public string Name { get; set; }
    public string Surname { get; set; }

}

void Copy()
{
  Person person = new Person()
  {
      Name = "A",
      Surname = "B"
  };
  
  DataPackage dataPackage = new DataPackage();
  dataPackage.SetData("my_format", person);
  Clipboard.SetContent(dataPackage);
}

But the line dataPackage.SetData("my_format", person); makes the app crash with message: "DataPackage doesn't support this type of data".
