Hi, I just upgraded a 4.1 site to 4.2 and it upgraded process went ok, but then I attempt to run the project with the project manager and before the site even loads in a browser I receive this message.

Could not load file or assembly 'Telerik.Sitefinity, Version=4.1.1395.0, Culture=neutral, PublicKeyToken=b28c218413bdf563' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Dear Charles

1395 is the number the number of 4.1 SP1.

Any custom code or controls in your solution that were build against that and would need to be updated.

Hi Charles,

As Markus suggested, the problem may be coming from custom controls of yours which need to be built using the new assemblies.

The following article may be useful to you:
