I am migrating web apps to new hosting servers, but when I try to access them to test on the new server, I get all these assemblies not found errors like:

Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Source Error:

Line 28:        <compilation debug="false">
Line 29:            <assemblies>
Line 30:                <add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

Does anyone know where you find these to install or how to migrate them over?

That's part of the ASP.Net AJAX kit.

  • That's included in the current version, but had to be separately installed on the web server for previous versions. – DOK Nov 10 '08 at 16:21
  • You will have to either install the ASP.AJAX kit on the server, or include the assemblies in your project. Here http://stackoverflow.com/questions/273418/any-way-to-use-aspnet-ajax-when-my-server-does-not-and-can-not-have-the-aspnet, – StingyJack Nov 10 '08 at 16:23
  • and here http://stackoverflow.com/questions/221761/how-do-i-force-aspnet-ajax-to-use-a-script-from-the-fs-and-not-webresourceaxd-o will say you how you can include the libraries as DLL or as JS. – StingyJack Nov 10 '08 at 16:24
  • Post those links as their own answer and you'll get at least one upvote, stingy. – Joel Coehoorn Nov 10 '08 at 16:24
  • BTW: my general SO strategy is to post a 'quick' answer first, and then "flesh it out" with reference links or details once the initial post is up there. In this case, I was having a much harder time than I thought finding the actual download locations. – Joel Coehoorn Nov 10 '08 at 16:26

You will have to either install the ASP.AJAX kit on the server, or include the assemblies in your project. This question and this question say you how you can include the libraries as DLL or JS.
