Unhandled Exception: System.Runtime.Serialization.SerializationException: The internal array cannot expand to greater than Int32.MaxValue elements. #146

Not an issue with this code, but with .Net. Posting here simply to help others if they run across the same issue. I encountered it when trying to use the included serialisation to do a binary save of a model.

This was fixed in .Net 4.7.2, but has to be enabled with a flag

Update App.config with

<runtime>
<!-- Use this switch to make BinaryFormatter fast with large object graphs starting with .NET 4.7.2 -->
  <AppContextSwitchOverrides value="Switch.System.Runtime.Serialization.UseNewMaxArraySize=true" />
</runtime>

Problem solved.
