I am updating my project from VS 202 to 2017 and also updating the Telerik version from 2012 to 2019
Also updating the .net Framework from 2.0 to 4.5. I have installed the Telerik version and added the reference but when I build I am getting the following error. I have also changed the web config with correct version name. What am I missing in the upgrade process?
'Could not load file or assembly 'Telerik.Web.UI, Version=2019.2.514.45, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxxx' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)'
