Error diagnostics

Hello,
Is there any way how to retrieve details about which XML fragment failed to deserialize?
When we're changing the XML structure and implement various converters to fix it so it's compatible from the legacy version it's hard to see which bits we have possibly missed. The de-serialization crashes with an exception that is extremely unhelpful.

Hi @jhranac have you tried the EnableMemberExceptionHandling method? It should provide better exception messaging when exceptions occur during deserialization. Example of this found here, along with being able to configure what happens when unknown content occurs:

A configurable and eXtensible Xml serializer for .NET. - home/Issue507Tests.cs at master · ExtendedXmlSerializer/home
Perfect!! That does exactly what I needed. Thanks!
Going through issues here and it looks like we have this one answered. Please do let me know if you have any further questions and I will do my best to assist. Closing for now.
