Using the version 15.2460.0.40 for my Syncfusion.Sfdiagram.wpf and Shared.WPF on windows 7, using VS 2015.

I simply launch the FlowDiagram_2015.sln in VS 2015.

The project compiles and runs as expected, but upon stopping and showing the project, I get:
"Object reference not set to instance of an object" for the entire <syncfusion:ConnectorCollection>tag and its entire contents. The connectors do not show in the vs designer and of course it is hampering further investigation, and killing my confidence ni adopting these controls.

Is it a setting perhaps in my project or VS settings? The problem is 100% repeatable using the VS 2012 project opened in VS 2012 as well as VS 2015.

Is there something missing in the code behind to initialize the collection?
