ASP.NET MVC 4 update controls to the lastest version

[Aaron Melo]

Hi, we have the license for the lastest version and we want to update our current proyect to this.

At the moment we installed Essential Studio version 12.1 and use the Assembly Manager.

We tried to copy manual the dlls to the solution but we got an error related with a missing reference "Syncfusion.XlsIO" but we already copied the dll and referenced it.

How can I fix it?

And what should be the best way for update the dlls without problems ?

Greetings

Hi Aaron,

Thank you for using Syncfusion products.

We suspect that the exception might be raised due to reference of improper assemblies between .Net frame work version and assembly version. Project frame work version should be higher than or equal to the assembly version (Say for an example if the assembly version is 12.1400 then .net frame work version should be 4 or higher).

Please let us know if you need any clarification.

Regards,
Prasanth
