Hello ,

Thank you for writing.

Our assemblies are built NET 2.0 NET 4.0. In order to successfully compile one the Telerik WinForms assemblies need to have the same version. The error message on your end suggests that you are referencing the Telerik.WinControls with version 2017.2.502.20, meaning .NET 2.0 while the other assemblies of your project are .40. 

Please check, remove the old reference and add Telerik.WinControls.dll with version 2017.2.502.40.

I hope this helps. Should you have further questions please do not hesitate to write back.

Regards,
Hristo
