Hello,
I've just updated to Reporting R3 2018 and I now have an exception when generating a PDF from a report, when a ReportProcessor instance is created. The exception message is the following:
[A]Telerik.Reporting.Configuration.ReportingConfigurationSection cannot be cast to [B]Telerik.Reporting.Configuration.ReportingConfigurationSection. Type A originates from 'Telerik.Reporting, Version=12.1.18.620, Culture=neutral, PublicKeyToken=a9d7983dfcc261be' in the context 'Default' at location 'C:\Temp\Temporary ASP.NET Files\vs\293ea1ac\b0f39161\assembly\dl3\a336f798\0099b611_b108d401\Telerik.Reporting.dll'. Type B originates from 'Telerik.Reporting, Version=12.2.18.912, Culture=neutral, PublicKeyToken=a9d7983dfcc261be' in the context 'Default' at location 'C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\Telerik.Reporting\v4.0_12.2.18.912__a9d7983dfcc261be\Telerik.Reporting.dll'.
Unfortunately, the release notes doesn't say anything about a change on this.
Can you please explain what needs to be done to make it work again?
