Where to get and how to install (or migrate) the absence of assemblies for ASP.NET server?

I am migrating web applications to new hosting servers, but when I try to access them for testing on a new server, I get that all these assemblies did not find any errors, for example:

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"/>
Line 31:                <add assembly="System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
Line 32:                <add assembly="System.Web.Extensions.Design, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

      

Does anyone know where you will find them, or how to transfer them?

This is part of the ASP.Net AJAX suite.

You need to either install the ASP.AJAX bundle on the server or include assemblies in your project. This question and this question tell you how you can include libraries as DLLs or JS.
