Steema Central

I'm using the WPF version of TeeChart.
I'm trying to save the chart with this code:
chart.Export.Template.Save(@"c:\test\chart.ten");

I get the following exception:

An unhandled exception of type 'System.Runtime.Serialization.SerializationException' occurred in mscorlib.dll
Additional information: Type 'Steema.TeeChart.Chart' in Assembly 'TeeChart.WPF, Version=3.5.3146.24806, Culture=neutral, PublicKeyToken=98e8c3f289a4e286' is not marked as serializable.

Hi John,

I could reproduce the issue here using build 3.5.3146.24806. However, it works fine using our current sources so you may expect this issue to be fixed on the maintenance release we are currently arranging and will be out immintently.
