Error message while saving a chart form

Question

When I save the form I get this error. It was working fine for long. I did not update any syncfusion controls or dll.

Hi Shahim, 
 
Greetings from Syncfusion.  
 
We have checked your query and we would like to suggest that the reported problem “While save the chart forms, shows error message” has been resolved by setting of CopyLocal property of all references to False in the application. Since, CopyLocal=true results in a copy of .dll being copied to the folder, this often causes VS .NET to inconsistently reference .dlls.
