We tried to upgrade the Prometheus RadControls to the new version released this week and now we get this error on all the instances of RadGrid and the project will not build.
Could not load file or assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
It seems there is some kind of error within the ASP.NET AJAX that Microsoft released a fix for, but this fix does not work for us:
Could not load file or assembly System.Web.Extensions, Version=3.5.0.0
Is it possible there is some kind of error within the new RadControls version that is pointing to the 3.5 version of .NET and not 2.0?
