Hi Malik, 

Greetings from Syncfusion. 

We suspect that the reported problem might be due to mismatched product version of Syncfusion assemblies. So, we request you to refer the same product version of Syncfusion assemblies across different projects (dependent ones) to resolve this issue. 

If still issue continues, kindly share us the csproj file of projects along with packages.config (if any) to investigate further on the reported problem.
