Hello,
I have a very simple MVC project setup with a code excerpt from the demo chart page. The MVC project compiles and runs fine, serving normal views without issue, however when I attempt to load the SyncFusion view I get the runtime error referenced by the subject. The error occurs whenever execution enters a method that references the MVCChartModel.Series property such as "chartModel.Series.Clear();" from the example code. Commenting out that line allows the program to execute, but the chart itself is of course useless without a series.
Further, when debugging it is possible to instantiate a new MVCChartModel object as a watch, and see/explore the Series property without any issue. I have run the project converter to setup appropriate references, and namespaces in the Web Config, but I cannot seem to locate a way to run the example code without error. The controller code and view code being executed are a copy/paste from:

Thanks.
