I have run into a problem after installing Visual Studio 2015 and importing a VS 2013 project that use Nevron Chart (2015).  I did not have this problem previously when using Nevron chart in VS 2013.

1) I have placed a Nevron Chart on a form and have docked it in a "Tab" panel. 

I can work with the form and chart in design mode, however, when I close and re-open the project I get an error that prevents me from viewing the form in design mode.
This is the error after closing and re-opening the project:



2) When I delete the automatically generated code the error goes away and I can view the form and chart in design mode but I loose the docking and other settings.

Deleting this code allows the designer to work again

3) These are the libraries referenced in the project:



Any suggestions?

Hi Allen,

This looks like VS problem - can you send a test project?
