Cannot use XmlSerializer dotnet-script

[Timo-Weike]

If I try to execute code like

using System.Xml.Serialization;
using System.IO;

[XmlRoot("root")]
public class MyXml
{
    [XmlAttribute]
    public string Name { get; set; } = string.Empty;
}

var text = File.ReadAllText("file.xml");

using (var stream = new StringReader(text))
{
    var deserialized = new XmlSerializer(typeof(MyXml)).Deserialize(stream);

    var value = deserialized is not null
        ? (MyXml)deserialized
        : default;

    Console.WriteLine(value);
}

I get the error

This is unfortunately a bug in the Roslyn compiler. The dynamic type names used are not compatible with the XmlSerializer. See https://github.com/dotnet/roslyn/issues/22859

I've just run into this issue. Is there a work around at all?
