Hi Richard ,
Thank you for using the syncfusion products.
While using the version 8.2.0.21 in MVC2 there is no hard dependencies. We could see that you are using older version of Essential studio . We highly recommend you to upgrade to newer version of Essential studio as it has enhanced with more features and support.

Please let us know if you have any clarification.
Thanks,
