How to resolve the error "...exists in both XlsIO.Base and XlsIO.Web"?

Platform: ASP.NET Web Forms (Classic) |
Control: XlsIO

* Apply to all versions not earlier than 6.4.x.x

This error occurs because of ambiguity between the assemblies. From version 6.4.x.x, medium trust support for ASP.NET platform is provided by Syncfusion.XlsIO.Web.dll. This ambiguity problem can be solved by referring XlsIO.Base alone in the application instead of referring both XlsIO.Base and XlsIO.Web.


In case of medium trust application, please use XlsIO.Web assembly.
