    Hi there,
    We are using Sitefinity 3.6 SP1
    At present we are moving our sitefinity based sites to new server.

    Here are the configration of both Server:
    Current Server

    Windows Server Web SP2
    It has .Net Framework 2.0 and 3.5 SP1 installed.
    IIS 7.0

    New Server

    Windows Web Server 2008 R2 SP1
    It has .Net Framework 2.0 & 4.0 installed.
    IIS 7.5

    Problem

    After Creating web site on the new server. We started testing using host file entry with IP address before change the DNS. During this test we got following error while access the site :

    Error
    :
    Could not load file or assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

    After some R & D we found that it could be due to following missing component :
    MS AJax Extenion 1.0 
    We believe siteinity uses it internally.
    We installed it on the new server but there was no change.
    MS .Net Framework 3.5 SP1
    We already have .Net 4.0 on new server so we are not sure whether to install .Net Framework 3.5 SP1 or not.

    Please do let us know what could be the reason for this error and how to fix it.

    Regards,
    Gaurav

    Hi Gaurav,

    You do not have a reference to System.Web.Extensions version 3.5. Please make a reference from your GAC explicitly.

    Hi Ivan Dimitrov,

    Thanks for your Feedback.

    .Net Framework 3.5.1 feature was not enabled in Server > Features list.
    We enabled .Net Framework 3.5 SP1 from Server Feature and installed .Net Framework 3.5 SP1 and it Fixed the error.

    Regards,
    Gaurav
