Names of types are not CLS-compliant which prevents `XmlSerializer` to work

[akade]

Describe the bug

Names of of Types are not CLS-compliant. Minimal repro:

using System.Xml.Serialization;
public class A{ }
new XmlSerializer(typeof(A));

will result in:

Error: System.ArgumentException: Identifier 'Submission#4' is not CLS-compliant. (Parameter 'ident')

Is there a workaround to get XmlSerialization working within a notebook?
