I have a web application developed in Visual studio 2005. I need to convert it to Visual Studio 2008. The problem is that the application is using crystal reports. When I'm trying to run a page with CrystalReportViewer I am getting the following error:
Could not load file or assembly 'System.Web.Extensions, Version=220.127.116.11, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
How do I solve this problem?
