ISerializer<DateTime> Doesnt work

[Shidzy2]

Im trying to add custom formatting for DateTimes
My code:

    public class XmlDateTimeSerializer : ISerializer<DateTime>

                IExtendedXmlSerializer serializer = new ConfigurationContainer()
                                .Type<DateTime>().Register().Serializer().Using(new XmlDateTimeSerializer() { Options = options})
                                .Create();

But Get and Write methods never called on serialization
Im also tried same as here in test:
https://github.com/ExtendedXmlSerializer/home/blob/master/test/ExtendedXmlSerializer.Tests.ReportedIssues/Issue477Tests_Extended.cs

But that solution also didnt worked - what im doing wrong here or is it bugged?

Hey there @Shidzy2 thank you for writing. Are you able to provide a complete sample (failing test is preferred) of what you are encountering? If I have a full code sample I can look into this further for you. 👍
