[CLOSED] Could not load file or assembly

Hello,
I've just upgraded my ext.net framework from ver 2.2 to ver 2.5.1. When I build the solution it doesn't display any errors, but when I run it, it displays the following error:

Could not load file or assembly 'Ext.Net.Utilities, Version=2.4.0.0, Culture=neutral, PublicKeyToken=2c34ac34702a3c23' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Hi @redi,

Please clarify, how did you upgrade? It looks you didn't upgrade Ext.Net.Utilities.dll.

There are some problems with dlls in v2.5.1 release. All the problems should be fixed with v2.5.2 which has been released a few days ago.
