Hi,

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)'

 

Thanks

It is fixed now. one of your old thread had solution.

Unblock the Telerik download zip file first and then use them to include in the project.

 

Thanks

Glad that you've managed to fix the error!

For reference I am pasting the link to the documentation below:

https://docs.telerik.com/devtools/aspnet-ajax/installation/upgrading-instructions/upgrading-a-trial-to-a-developer-license-or-to-a-newer-version#could-not-load-file-or-assembly-telerikwebui-after-upgrade

Keep up the good work!

Regards,
