Hello,

we are encountering a huge memory consumption when opening and closing charts repeatedly.
After closing a chart, only a part of the allocated memory is released, so the overall memory usage rises more and more
with each opening of a chart.
We did some investigation using WinDbg and found out, that even in a simple example with just creating a chart control and
closing it the chart control is not released. We saw that it is still registered to a ShutDownStarted-event (Nevron.Chart.Wpf.NChartControl.Dispatcher_ShutdownStarted(System.Object, System.EventArgs).
I attached an example with an extra text file with some information from WinDbg (Info_WinDbg.txt).
Is there any solution? What can you recommend for best cleanup?

Thank you and best regards,
Michael Krüllmann
