Compiler Error Message: CS0433: The type 'System.Web.UI.UpdatePanel' exists in both 'c:\WINDOWS\assembly\GAC_MSIL\System.Web.Extensions\18.104.22.168__31bf3856ad364e35\System.Web.Extensions.dll' and 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\7073199f\ac695c9f\assembly\dl3\b2531efd\00b86e4c_ff3cc701\System.Web.Extensions.DLL'
If I am getting a lot of these, or the same error over and over, even after deleting all sub items in my Temporary ASP.NET Files folder...what is likely the problem here?
How do I fix this, both quickly....and also permanently?
This is very frustrating, as the files (or folders!!!!) are often locked and I have to find the process and kill it, usually inetinfo.exe.
I have published on other hosted environments and not had this problem with conflicting DLLs
