I have an ASP.net 4.0 website that uses Telerik controls. Recently the past dev who is no longer with the company upgraded the Telerik controls version.

The website works great locally and after i publish it and move it to my DEV environment(previous site wiped out and replaced with entire published new site) it works great with no issues.

As soon as i move the published version to production it errors every single time, with the following message(screenshot attached):

Could not load file or assembly ‘Telerik.Web.Design, Version=2011.2.915.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4’ or one of its dependencies. The system cannot find the file specified.

I know the DLL exists there and is the same version “2011.2.915.40”. I am really stumped as i have moved this back and forth and for some reason it only errors once moved to prod?

    So i feel really stupid, but i had to add the Telerik.Web.Design.dll to the bin on Prod. The weird part is the DLL was never part of this project and locally and DEV worked great.

    I did a search on my computer, found it and then added it. Not sure why Local and DEV worked without it, but its now fixed that i added it to the BIN.

    Telerik.Web.Design.dll
