If a public field (or property) has the datatype "decimal" and a "DefaultValue(0.0)" (which is a "double"), then the serializer will throw an "InvalidProgramException" during serialization!

Here is a small repo-code:

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

namespace ConsoleApplication1
  public class Program
    static void Main()
      new XmlSerializer(typeof (Program)).Serialize(new StringWriter(), new Program());

    public decimal Value;

Thanks for reporting this issue. There're several work around for this issue.
1. Use 0 instead of 0.0 as the default value.
2. Use the old serialization generator (add useLegacySerializerGeneration="true" to the config)
3. Use double instead of decimal here.
