The “'System.Web.Extensions” is the Strong Named assembly that should be installed in GAC, the file not found issue should not caused by the relative path problem of the sub directory. In my opinion, the problem is the AJAX 1.0 extension is not installed
on the server.
To solve this issue, we can remove the “1.0.61025.0” version “System.Web.Extensions” assembly from the “assemblies” section. As you said, after doing that, the LINQ assembly not found issue appears. For this issue, I would recommend checking if .NET Framework
3.5 installed on the Server.
