    Hi,
    i am getting the following error

    Could not load file or assembly 'Telerik.Web.UI, Version=2010.1.309.35, 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)

    Hello Deepak,
    I am sorry to hear you are experiencing such issues.

    The most common cause for the issue you experience is an old Register node in an .aspx or .master file. You could use the Find and Replace dialog to look for "2010.1.309" and remove any leftover Register nodes.

    Referencing a project or assembly, which uses a version of Telerik.Web.UI, different than the one your current project references could cause the issue you experience as well. If that is the case, you could do one of two things: 
    • Add an appropriate binding redirect to your web.config (more info)
    • Recompile your dependent assembly using the latest Telerik.Web.UI.dll

    Please do not hesitate to contact us if you experience any further issues.

    Best regards,
    Andrey
