Today I received this error;
Cannot save 'C:\Projects\<SolutionFolders>\<NameOfItinerary>.itinerary': Type 'System.Xml.XmlNode' in Assembly 'System.Xml, Version=18.104.22.168, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable.
As stated in the Biztalk social forum ;
- Somehow one of the shapes led to a corrupted itinerary
- Remove the shapes one by one to identify the one generating the error
- Recreate the shape
- It now works…magic!
Also make sure that everything is properly deployed (when using an orchestation extender) before changing the itineraries.
