How do I solve this error in my application when I put it on my server?

Question

When I deploy my ASP.NET application to my server I get this error: add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

I have installed IIS and AJAX but this error occurs anyway.

What am I doing wrong?

Answer 1

Is the System.Web.Extensions.dll in the same place on the server as it was on the client machine? Try copying it to the solution bin directory on the server.

Answer 2

Do you have the correct versions of .Net installed on the server.

Your app appears to be targetting the .Net 1.1 version of the System.Web.Extensions dll. Is this version of the framework installed on your server?
