I can't seem to get I'm working on a project and hit a roadblock. I've looked through the documentation and I'm still confused about I'm having trouble with deserializing an XML document that contains DateTime fields in .NET 6 using `XmlSerializer`. The XML looks like this: ```xml <Events> <Event> <Name>Sample Event</Name> <StartDate>2023-10-01T14:30:00</StartDate> <EndDate>2023-10-01T16:30:00</EndDate> </Event> </Events> ``` I defined the corresponding C# classes as follows: ```csharp [XmlRoot("Events")] public class Events { [XmlElement("Event")] public List<Event> EventList { get; set; } } public class Event { public string Name { get; set; } public DateTime StartDate { get; set; } public DateTime EndDate { get; set; } } ``` When I try to deserialize the XML using the following code: ```csharp var serializer = new XmlSerializer(typeof(Events)); using var reader = new StringReader(xmlString); var events = (Events)serializer.Deserialize(reader); ``` I encounter the following exception: `System.InvalidOperationException: There is an behavior in XML document (2, 21).` It points to the `StartDate` element, which is perplexing because the format seems correct according to ISO 8601 standards. I've also tried different formats for the date, such as using only the date or including time zone information, but nothing seems to work. I've verified that the input string is valid XML, and I've checked for any discrepancies in the casing or spelling of the XML elements. Could this be a serialization scenario in .NET 6, or am I missing something in the way the `XmlSerializer` handles DateTime? I would appreciate any insights on how I could resolve this scenario or transform the date format before deserialization. My development environment is Ubuntu. Has anyone else encountered this? This is happening in both development and production on macOS.
