Serialization Exception - Docking/MDI for WPF Forum

Posted 12 years ago by John Doherty

Version: 11.1.0542

I am receiving the following exception when attempting to serialize a DockSite implemented using MVVM. MyModel is serializable. Is there a way around this?

Thanks,

John

Hi John,

In your error's case, I don't believe it's possible to serialize generic types with XamlSerializer. If you make a class that inherits your DeferrableObservableCollection<MyModel> type and use that class instead, it may work around this particular issue.

That worked, thank you!

The latest build of this product (v24.1.2) was released 5 months ago, which was after the last post in this thread.
