Hi,

I have just upgraded my application to "2009.3.1208.20" from "2009.2.826.35". Its geeting compiled without any errors, however at runtime while loading the first page its throwing following error -

"Could not load file or assembly 'Telerik.Web.UI, Version=2009.2.826.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"

I have not used any version reference for Telerik dll. Also I have cleared "Temporary ASP.NET Files" from framework folder.
Reset IIS done. Reset system is also done :( But I could not get any success. I am just wondering, for what reason its trying to look for older version. Pasting web.config values here. Please help.

Hi Vinayak ,

After upgrading your project to another version, you should update not only the Telerik.Web.UI.dll in the /bin folder, but also the DialogHandler and SpellCheckHandler httpHandlers declarations in web.config file:
I recommend you check this knowledge base for additional information:.
