is it manadatory to install Ajax extensions in deployment server ?

Question

Hi,

I have installed Ajax in my local machine for development (VS 2005). its working fine in local machie. when i deploy the code in server its throwing an error stating `

"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. (D:\Inetpub\wwwroot\NBCU ITAM Application\NBCUITAMWS\web.config line 45)".

Is this error because of not installaing ajax in server ?

thanks, Jebli
